Thirteen athletes at six college basketball programs: Arizona State, Eastern Michigan, Temple, New Orleans, North Carolina A&T, and Mississippi Valley State, are being investigated for sports betting violations.

According to CBS Sports, the NCAA's enforcement staff allegedly discovered that some student-athletes were "betting on and against their own teams," among other point-shaving allegations.

In a statement,  the NCAA confirmed the discovery of the allegations.

"Through the NCAA's extensive integrity monitoring program and network of sources, the enforcement staff became aware of unusual betting activities around regular-season games played by these teams," the NCAA announced in a release. "The enforcement staff followed up on those reports and substantiated -- in some cases, via text messages, direct messages on social media platforms, and other material evidence -- that violations had occurred."

The NCAA added that the schools and current coaching staffs are "not alleged to have been involved in the violations." 

On Thursday, Arizona State University released a statement about the investigation.

"Arizona State University is aware of the NCAA investigation and outcome related to a former student-athlete who is no longer enrolled at ASU,” the statement read. “The university cooperated fully with all inquiries and was not implicated in any way."

The latest NCAA gambling news follows the announcement that Mykell Robinson, Steven Vasquez, and Jalen Weave, who all played for Fresno State before Vasquez later transferred to San Jose State, were banned from college basketball for being involved in sports-betting game manipulation.

According to the NCAA’s findings,  Robinson, in a text message to Vasquez, planned to “underperform in several statistical categories during one regular-season game.” Robinson, Vasquez, and a third party bet a combined $2,200 on Robinson for his under-line performance in those categories and won a $15,950 payout, which they all split.

“As part of a coordinated effort, the student-athletes bet on their own games, one another’s games, and/or provided information that enabled others to do so during the 2024-25 regular season,” a Wednesday NCAA press release states.
