The NCAA asked a Texas appeals court Monday to stay a temporary injunction that cleared the way for Texas Tech quarterback Brendan Sorsby to play this fall despite being declared ineligible for gambling while the Big 12 Conference filed a federal lawsuit warning the Texas attorney general to stay out of a case that has rattled college sports.

The filings in separate courts raised the stakes in the fight over whether Sorsby can play and who makes that decision.

In documents filed with the Court of Appeals for the Seventh District of Texas at Amarillo, the NCAA asked for an emergency motion to stay the June 8 injunction granted by a Lubbock County court in favor of Sorsby, who has admitted he has a gambling addiction and has made thousands of bets, included some on his own team when he was a freshman at Indiana.

The NCAA also asked for a resolution of the case by Aug. 28, which it said would spare the potential disruption of a ruling after Texas Tech begins its season on Sept. 5. The NCAA has long banned players for gambling but Texas Tech says Sorsby, who transferred there in January after the past two seasons at Cincinnati, would be better off on the team for his mental health and well being.

“The trial court’s temporary injunction sweeps beyond anything Texas law permits,” attorneys for the NCAA wrote. “It undermines the integrity of college sports, rewrites member-adopted rules of the National Collegiate Athletic Association, immunizes Brendan Sorsby from discipline for admitted and serial violations of NCAA anti-gambling rules, incentivizes a run on courthouses across the country to challenge even the most obvious and straightforward student-athlete eligibility decisions and demolishes the status quo.”

The injunction last week from Judge Ken Curry prevents the NCAA from being able to block the Sorsby’s eligibility for what will be his final college season with a team among the favorites to win the Big 12 and return to the College Football Playoff for a second consecutive season.

The Big 12, meanwhile, filed suit in U.S. District Court in Dallas seeking a court order backing its ability to use its bylaws for potential punishment against Sorsby. So far, the Big 12 has not weighed in on the Sorsby case but last week the Texas attorney general’s office warned the league of potential legal action from Texas Tech for any sanctions against the school or Sorsby.
