Major League Soccer (MLS) has permanently banned two Ghanaian-born former players, Derrick Jones and Yaw Yeboah, after uncovering extensive gambling activities involving bets on MLS matches, including those featuring their own teams. This announcement came 42 days after MLS unveiled a partnership with Polymarket, a prediction platform that enables users to wager on a wide range of events, from sports outcomes to geopolitical incidents.
Details of Players’ Contracts and External Club Context
Derrick Jones had his contract option declined by the Columbus Crew on November 26, whereas Yaw Yeboah’s contract with LAFC was mutually terminated on January 16 before he signed with Qingdao Hainiu, a club competing in the Chinese Super League. Notably, Qingdao Hainiu was part of a group of nine Chinese Super League teams that began the season carrying points deductions due to prior match-fixing, bribery, and corruption violations.
Investigation Uncovers Manipulation and Information Sharing
The league’s integrity partners alerted MLS to suspicious betting patterns, prompting an investigation by a contracted law firm. The inquiry revealed that during the 2024 and 2025 seasons, Jones and Yeboah engaged in significant gambling on matches, including bets on in-game events such as whether Jones would receive a yellow card in a match on October 19, 2024, which he did. The players also disseminated details about their manipulation of these match events to other gamblers. Following the October 2025 launch of the investigation, both players were placed on administrative leave.
League’s Prior Awareness and Controversial Partnership Timing
MLS was evidently aware of ongoing vulnerabilities related to match manipulation before publicly announcing its deal with Polymarket. This overlap raised concerns over the optics of promoting a betting partnership amid unfolding allegations of match-fixing within its ranks. Despite this, the league proceeded with the agreement, with Deputy Commissioner Gary Stevenson defending the move as a step to innovate fan engagement, stating,
“As MLS continues to grow, innovation remains central to how we engage fans and evolve the league,”
and adding,
“Partnering with Polymarket allows us to integrate prediction markets as a new fan engagement format and position MLS as an early leader among global soccer properties.”
The Risk of Betting Partnerships to Sport Integrity
The suspensions and the Polymarket deal, while not directly linked, exist on the same trajectory reflecting MLS’s shifting relationship with the betting industry. Following the 2018 U.S. Supreme Court decision that allowed states to legalize sports betting, sports leagues began embracing these new revenue streams despite the inherent risks. MLS’s engagement with gambling, an industry reliant on preserving a façade of integrity, introduces complex challenges, exacerbated by players’ vulnerabilities to betting temptations.
Previous Gambling Enforcement and Player Demographics
The league has prior experience with player gambling infractions. Midfielder Felipe Hernández of Sporting KC was suspended in 2021 for gambling violations, reinstated, and subsequently caught betting again in 2024, leading to contract termination. Hernández’s actions did not compromise match integrity, but his case underscores the difficulties MLS faces in curbing gambling violations, especially given that the league’s predominantly young, male demographic aligns with the target audience of betting platforms.
Commissioner Garber’s Statement on Commitment to Integrity
In response to the scandal, MLS Commissioner Don Garber reassured fans of the league’s dedication to upholding the sport’s integrity:
“Major League Soccer remains steadfast in its commitment to match integrity,”
he stated, continuing,
“The league will continue to enforce its policies, enhance education efforts, and advocate for the elimination of yellow card wagering in all states to protect the integrity of our competition for clubs, players, and fans.”
Challenges in Restoring Trust Amid Growing Legal Gambling
Despite these reassurances, the effectiveness of enforcement and education efforts remains questionable. Each reported incident chips away at public confidence in MLS matches, leaving fans doubtful about the authenticity of the competition. The league’s focus on combating specific betting types, such as yellow card wagers, addresses symptoms rather than the underlying problem, as match-fixers are likely to shift tactics rather than cease illicit activities altogether.
Implications for MLS and the Future of Sports Betting
The involvement with Polymarket, a prediction market platform, at a time when MLS is grappling with a public betting-related scandal, amplifies concerns over the league’s sincerity in protecting its competitive integrity. The contradiction between promoting fan engagement through legal betting and simultaneously enforcing gambling prohibitions on players presents a fraught and precarious balance. The widening acceptance of sports betting by leagues like MLS underscores a broader ethical debate about the risks posed to sports culture and fairness, raising urgent questions about how to safeguard the game amidst commercial pressures.
