South Africa midfielder Themba Zwane’s controversial red card against Mexico has been identified as one of several incidents from the 2026 FIFA World Cup that may warrant further investigation, according to an independent sports integrity body.
A report by The Athletic revealed that Zwane’s dismissal was one of seven incidents highlighted by the Group of Copenhagen, an advisory body operating under the Council of Europe that monitors betting activity and unusual events in sport.
The organisation issued what it describes as “yellow notices”, indicating that certain incidents appeared irregular enough to justify additional scrutiny. However, the group has stressed that these notices do not constitute evidence of match manipulation or wrongdoing.
FIFA has rejected any suggestion of irregularities, with its Integrity Task Force, which worked alongside the Group of Copenhagen during the tournament, concluding that it found no signs of manipulation or suspicious activity.
The Group of Copenhagen has not yet published its full report and has offered no detailed explanation as to why Zwane’s sending-off was singled out.
The veteran midfielder was dismissed after being adjudged to have struck a Mexican opponent in the face while attempting to shield the ball. South Africa later appealed the resulting three-match suspension, arguing that the punishment was excessive, but the ban ultimately ruled Zwane out for the remainder of the tournament.
Several other incidents from the World Cup were also flagged by the advisory body, including the decision to overturn Folarin Balogun’s suspension ahead of the United States’ match against Belgium, substantial betting activity surrounding Spain’s goalless draw with Cape Verde, and a lengthy VAR review that led to Ferran Torres’ goal being disallowed during Spain’s 4-0 victory over Saudi Arabia.
Sports betting integrity expert Christian Kalb urged caution when interpreting the findings, explaining that unusual betting patterns do not automatically indicate corruption.
He noted that irregular market movements can often be explained by legitimate factors such as changing odds or hedging strategies, adding that investigators must carefully distinguish between suspicious activity and normal betting behaviour.
While the Group of Copenhagen’s observations have prompted renewed discussion about sporting integrity, there is currently no evidence to suggest that any of the highlighted incidents involved match-fixing or manipulation. The full report is expected to provide further insight into the cases under review.
