Overview

  • Screenshots of two Nov. 20, 2022 Venmo transactions showed memos reading “sports gambling,” including one referencing the UCLA vs. USC game.
  • Mateer said the memos were inside jokes unrelated to actual wagering, insisting he has never bet on sports.
  • Oklahoma’s athletic department said its compliance office has been notified; it uses ProhiBet monitoring; it said no NCAA investigation is pending.
  • The screenshots, initially shared by a Barstool Longhorn account, have been deleted or made private; their authenticity remains unverified.
  • Under NCAA rules, proven sports gambling by student-athletes can lead to required education programs or the loss of up to half a season of eligibility.
