Oklahoma starting quarterback, John Mateer, has denied ever being involved with gambling after screenshots of past references to "sports gambling" on his Venmo account surfaced online Monday.  He claimed on Tuesday it was harmless "inside jokes" with his friends.

School officials became aware of the screenshots late Monday night and are looking into the situation, a source told ESPN's Pete Thamel.

"The allegations that I once participated in sports gambling are false," Mateer posted to X on Tuesday. "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. I understand the seriousness of the matter but recognize that, taken out of context, those Venmo descriptions suggest otherwise. I can assure my teammates, coaches, and officials at the NCAA that I have not engaged in any sports gambling."

Mateer allegedly included "sports gambling" in memos for transactions on Nov. 20, 2022, while he was a freshman at Washington State.
