Oklahoma quarterback John Mateer has become the subject of intense scrutiny after screenshots of his Venmo activity circulated online. On Monday, images posted to X, formerly Twitter, showed Mateer’s payment history containing references to “sports gambling.”
The posts immediately raised concerns about potential NCAA violations, since the governing body strictly forbids athletes from wagering on their sport. The controversy has placed the Sooners program in an uncomfortable spotlight as questions grow about player awareness of compliance rules and the consequences of digital transactions that suggest gambling behavior.
Brent Venables Responds as John Mateer’s Venmo Activity Sparks Controversy
The NCAA prohibits athletes from betting on their own sport, immediately raising concerns over potential violations by Mateer. Mateer responded on Tuesday with a statement on his X account denying the allegations.
“The allegations that I once participated in sports gambling are false. My previous Venmo descriptions did not accurately portray the transactions in question but were instead inside jokes between me and my friends. I have never bet on sports,” Mateer wrote.
The transactions in question dated back to his freshman year at Washington State. Head coach Brent Venables addressed the situation following practice on Friday. Asked if the controversy allowed him to reinforce rules with his players, Venables noted that discussions had already occurred.
“Yeah, we’ve done, you know, we’ve already did that several weeks ago,” Venables said.
“But they’re they’re kids, you know, in many ways and you got to continue to educate non-stop, you know, as far as the rules and expectations.”
Venables emphasized that the lesson remains important for the team, while Mateer has moved past the situation.
“He recognized, as he’d be the first one to tell you, the enormity of maybe of what you the implications could have been had he not followed the NCAA rules years ago or whatever,” Venables said. “But you know, he just kind of, I don’t want again, he’s moved on quickly.”
The Sooners’ coach also shifted attention to Mateer’s role on the field, underscoring the quarterback’s leadership and impact on the offense.
“I would be negligent if I didn’t say it starts and ends with a quarterback,” Venables said. “Any good offensive unit, you know, you got to have good quarterback play and we’ve had that. Starts with the leadership, the work, the investment, the consistency, handling the good and the bad. John is a great leader. He’s natural. All the things that we’ve been talking about. So everything starts with him.”

Venables added that the Sooners’ offensive line has shown cohesion and toughness through camp, crediting the players and staff for their daily work.
“I like the camaraderie, the cohesion, the chemistry, the mindset, the toughness of the guys up front,” he said. “They’ve done a wonderful job taking ownership of all of their work every single day.”
The controversy placed Mateer in a difficult spotlight, but both his denial and Venables’ remarks framed the issue as a reminder of how quickly off-field matters can escalate. For Venables, the priority remains keeping players informed and prepared.
