The Gophers are heading into their biggest nonconference test of the season, at Texas Christian, knowing quarterback Mitch Leidner's status is in doubt.
Leidner has a sprained medial collateral ligament in his left knee, sources familiar with the injury confirmed Sunday.
The good news for the Gophers is it's not a torn anterior cruciate ligament, an injury that already has ended the season for tight end Duke Anyanwu and defensive tackle Scott Ekpe.
The bad news is that Leidner could still be sidelined for multiple weeks, perhaps into the start of Big Ten play, depending on the injury's severity.
"Any time you have a knee [injury], you're concerned," coach Jerry Kill said Sunday, while awaiting an update from the medical staff. "We haven't had a lot of good luck [with recent knee injuries]."
Kill said he might not give an update on Leidner's status until Thursday, when the team releases its official injury report and depth chart.
If Leidner can't play at TCU, the Gophers would turn to Chris Streveler, a redshirt freshman who has thrown one college pass. Kill said Jacques Perra, a walk-on from Roseville, has climbed to No. 3 on the depth chart.
"We're trying to redshirt [Perra]," Kill said. "If it was today, that's what we'd do because we're trying to redshirt Dimonic [Roden-McKinzy], and Jacques had a great camp, and throws the ball very well and does a good job."
