A gambling ring currently under federal investigation for its role in two NBA betting cases also was involved in unusual wagering activity on at least three men’s college basketball programs this season, sources told ESPN on Monday.

Sportsbook accounts connected to the gambling ring bet against North Carolina A&T, Mississippi Valley State and Eastern Michigan in games this season, sources said.

Some of the same accounts also placed large wagers on prop bets involving former Toronto Raptors player Jontay Porter in two games during the 2023-24 NBA season and veteran guard Terry Rozier in 2023, when he was with the Charlotte Hornets, sources said. Porter has admitted to manipulating his performance during the games for gambling purposes; Rozier has declined to comment on a reported investigation into unusual betting on his performance in a select game.

The sportsbook accounts linked to the gambling ring also wagered on a Temple game flagged for suspicious betting last March. Sources familiar with the ongoing investigations said the ring targeted additional college basketball programs over the past two seasons.
