Suspicious betting alerts were investigated by the MLS who said the two players engaged in extensive gambling on matches, including on their own teams, during the 2024 and 2025 seasons.
The violations included Jones' time at Columbus and Yeboah's stints with the Crew in 2024 and LAFC in 2025.
In one instance, both players wagered on Jones receiving a yellow card during the Crew's 3-2 win at the New York Red Bulls in an October 19, 2024 match, which he did.
Investigators also determined that the pair likely shared confidential information with other gamblers about their intent to draw bookings, though no evidence emerged that any of the activity influenced the outcome of matches.
Commissioner Don Garber said in a statement that the MLS "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."
