Georgian rugby shaken by new doping scandal: players punished for urine sample substitution
Georgian rugby is facing one of the most serious doping cases in the sport's recent history after World Rugby and the World Anti-Doping Agency, WADA, confirmed sanctions against six players and one member of the support staff of the Georgian men's national team. According to announcements by World Rugby and WADA, the investigation named Operation Obsidian uncovered a scheme of urine sample substitution, as well as cases in which players received advance information about upcoming doping controls. The case is additionally serious because it does not concern only the conduct of individual athletes, but also failures within the Georgian anti-doping system. Because of the investigation's findings, WADA announced that it had lost confidence in the work of the Georgian Anti-Doping Agency, known by the abbreviation GADA, while the report stated that the findings had been forwarded to Georgian public authorities. According to available information, further steps toward GADA depend on measures to be taken by Georgian authorities, and WADA warned that an expedited procedure for determining non-compliance with anti-doping rules could also be initiated.
The harshest penalty for the former national team captain
The longest individual sanction was given to former Georgian captain Merab Sharikadze, who was handed an 11-year ban from participation in rugby. World Rugby announced that Sharikadze was among the six players sanctioned for breaches of anti-doping rules connected with sample substitution and interference with the testing process. According to reports citing World Rugby decisions, Giorgi Chkoidze was punished with a six-year ban, while Lasha Khmaladze, Otar Lashkhi and Miriani Modebadze each received three-year suspensions. Lasha Lomidze was punished with a nine-month ban. Former national team doctor Nutsa Shamatava was punished with a nine-year ban because of her role in the system of informing players about doping controls and organizing sample substitution.
According to World Rugby's announcement, the sanctions include a ban on all rugby-related activities, and the suspensions are counted from earlier provisional measures imposed after the proceedings were initiated. Sharikadze had a particularly prominent status in Georgian rugby because for years he was one of the best-known national team players and a symbol of the generation that brought Georgia closer to the top of European rugby outside the wealthiest unions. World Rugby had previously stated that Sharikadze was among the players with more than one hundred appearances for the national team, and in a sporting context Georgia's victory over Wales in 2022 was especially remembered. That is precisely why his punishment attracted the greatest international attention, although the seriousness of the case goes beyond one playing career.
How the sample substitution scheme was uncovered
According to World Rugby, the investigation was launched after irregularities were noticed in urine samples in the athlete biological passport programme from the period before the 2023 Rugby World Cup in France. World Rugby then informed WADA, and the two organizations carried out an extensive joint investigation that included targeted testing of players, DNA analysis and comparison with older samples stored in the long-term sample storage programme. In its announcement, WADA stated that the investigation confirmed five cases of sample substitution. Under anti-doping rules, such practice falls among prohibited methods because it directly undermines the credibility of the testing process, regardless of which substance was being concealed.
A particularly important part of the investigation concerned DNA comparisons. According to World Rugby statements reported by international media, analysis established that certain samples did not match the DNA profile of the athletes who had officially submitted them. In three cases, according to published findings, the samples matched the DNA profile of Merab Sharikadze and related to other players. According to World Rugby, this confirmed that the matter was not an administrative error or a procedural failure, but an actual substitution of samples. The investigation covered a period that public reports connect with the years before and around Georgia's appearance at the 2023 World Cup, with samples from 2022 and 2023 being analyzed in particular.
No confirmation of concealing performance-enhancing doping
Although the investigators' initial assumption was that sample substitution could be connected with concealing performance-enhancing substances, World Rugby announced that the extensive investigation found no evidence to support that hypothesis. According to World Rugby, there was credible evidence supporting the players' claims that the sample substitutions served to conceal the use of substances that were not intended to improve performance, primarily cannabis and tramadol. That circumstance does not reduce the seriousness of the offence because anti-doping rules treat sample manipulation, attempted manipulation and interference with control particularly strictly. In sports law, such actions are considered an attack on the monitoring system itself, not only on an individual test result.
Tramadol had for years been the subject of debate in sport because of its use as a strong analgesic and the health risks for athletes, and the World Anti-Doping Agency added it to the Prohibited List as of 1 January 2024. Cannabis is also treated in the anti-doping system according to rules that distinguish between the period out of competition and during competition, but an attempt to substitute a sample remains a separate and more serious offence. Under WADA rules, a prohibited method includes manipulation or attempted manipulation of any part of doping control. That is why in this case the central question became who enabled the sample substitution, how information about testing leaked to the national team and whether the Georgian anti-doping system can be considered credible without deep changes.
The role of the national anti-doping agency under special scrutiny
The most serious institutional part of the case concerns the Georgian Anti-Doping Agency. WADA announced that GADA employees gave advance notices about testing to players of the Georgian national team, which is contrary to the basic purpose of no-notice doping controls. According to WADA's report, the problem was not limited only to players and members of the national team, but also concerned persons responsible for implementing the anti-doping programme. The report states that failures were observed in the direct witnessing of sample provision, as well as actions that could have enabled or concealed urine substitution. Such findings are especially sensitive because national anti-doping organizations must operate independently and carry out controls in such a way that athletes do not have an opportunity to prepare in advance to evade a test.
In its public announcement, WADA emphasized that because of the findings from Operation Obsidian it had lost confidence in the Georgian anti-doping programme. In the management report of WADA's Intelligence and Investigations department, it was stated that the findings had been delivered to Georgian public authorities because of the continuing risk to the integrity of the anti-doping programme in the country. According to the same report, the measures of the Georgian government will determine whether WADA's compliance department will consider an expedited procedure against GADA under the rules on compliance with the Code. For now, it has not been officially confirmed that GADA has already been replaced by a new institution, but WADA's announcements indicate that thorough changes in the system are expected from the competent authorities. WADA president Witold Bańka assessed, according to agency reports, that comprehensive changes to the competent bodies must be carried out.
Consequences for the Georgian Rugby Union
World Rugby announced that the Georgian Rugby Union accepted the charge of misconduct and agreed to a sanction that includes a financial penalty and the implementation of reforms in the area of anti-doping education and prevention. The amount of the financial penalty was not publicly stated in all official announcements, but international media reported that it is a significant penalty. According to World Rugby, the union must implement an action plan that would reduce the risk of similar events recurring, which includes strengthening the education of players and staff about anti-doping obligations. Such an approach shows that the international federation is not treating the case only as a series of individual disciplinary matters, but as a problem of governance and culture within the national team system.
In recent years, Georgia has become one of the most important rugby national teams outside the traditional circle of the most powerful nations. According to World Rugby, the national team has already secured participation at the 2027 Rugby World Cup in Australia, and international reports state that the current scandal does not for now affect its right to participate in future competitions. Still, the reputational damage to Georgian rugby is considerable. The case comes at a moment when the sport in the country is trying to position itself further on the international stage, and Georgia will in 2026 host the expanded World Rugby U20 Championship. Therefore, every next step by Georgian sporting authorities will also be viewed through the question of confidence in the organization of international competitions.
Why the case is important for the global anti-doping system
Operation Obsidian is important beyond Georgian rugby as well because it shows how the modern anti-doping system increasingly relies on long-term sample storage, biological passports and forensic methods. In its announcement, WADA emphasized that the case shows the importance of storing samples over a longer period, because irregularities can sometimes be detected only through later analysis or data comparison. World Rugby emphasized that the investigation was science-led and that it included coordination of biological profiles, testing and long-term sample storage. Such a model becomes especially important in cases in which a classic positive test is not sufficient or there is suspicion that the sample collection process was compromised before laboratory analysis.
After the Georgian case, WADA stated that it had secured samples of athletes from other sports in Georgia and that an expert review of related biological passports was under way. If suspicions of substitution arise in other samples, WADA announced that it would notify the competent anti-doping organizations and guide them through the process of DNA analysis and comparison. This potentially expands the investigation beyond rugby, although there are currently no publicly confirmed findings showing that the same methods were used in other sports. WADA also connected the case with the earlier Operation Arrow, a 2020 investigation dealing with urine substitution in weightlifting, which emphasizes that sample manipulation has been recognized as a serious and recurring risk in international sport.
Institutional trust will be harder to rebuild than sporting results
For Georgian rugby, the short-term consequences are already clear: six players and one member of the support staff have been removed from the sport for a longer period, and the union must pay a penalty and implement anti-doping reforms. In the long term, however, the more important question is whether confidence in the testing system in Georgia can be restored. If the national anti-doping agency cannot guarantee independence, confidentiality of notifications and proper sample collection, then the credibility of all control results is threatened, even those involving athletes who are not suspected of anything. That is precisely why WADA's pressure on Georgian authorities has broader significance than rugby itself. The case has become a test of the ability of state and sporting institutions to show that an anti-doping programme can function without leaks of information, without the interests of national teams and without procedural weaknesses that enable manipulation.
According to currently available information, it has not been officially confirmed that Georgia will lose the right to participate in major competitions because of this case. However, the reputational burden will remain present until it is shown that real reforms have been implemented and that the persons involved in the failures have been removed from control procedures. World Rugby stated that the case shows the importance of a robust, science-led anti-doping programme, and WADA made it known that it would monitor the response of Georgian authorities. In such circumstances, the coming months could be decisive for the future of GADA, but also for the credibility of Georgian sport in the international anti-doping system.
