The UTEP Miners will be without their starting quarterback Friday when they host the Arizona Wildcats.
Head coach Sean Kugler announced Tuesday that junior quarterback Ryan Metz is out indefinitely with a shoulder injury.
Senior Zack Greenlee will likely be the starter, though redshirt freshman Mark Torrez could play, too.
Metz has made 14 career starts, and threw for 1,375 yards, 14 touchdowns, and four interceptions last season while completing 64.7 percent of his passes.
He was 28 for 51 for 259 yards and a touchdown this season before getting injured.
