Arizona Wildcats quarterback Bryson Beirne will undergo an MRI today to determine the severity of a knee injury suffered in Saturday's scrimmage.
Beirne, a senior and the backup to starter Nick Foles, twisted his right knee shortly after taking a snap in Saturday's workout at Fort Huachuca. He was replaced by Rutgers transfer Tom Savage, who finished the scrimmage with the second-team offense.
Sporting a heavy brace on his knee, Beirne watched this morning's practice from the sidelines.
Coach Mike Stoops said doctors are "not sure" of the severity of the injury, but will have a better idea after the MRI is performed.
"We'll wait until this afternoon, then we'll determine where we go from there with him personally and the position," he said.
It's too soon to tell what Beirne's injury means for Matt Scott, who is planning to redshirt this fall in order to potentially start in 2012. If Beirne is unavailable and Scott is intent on redshirting, the UA would have just one backup quarterback - true freshman Daxx Garman.
Stoops said he was disappointed to see Beirne injured.
"If it's a longterm injury ... we lose an awfully good player who's been playing really well," he said. "This was his opportunity to play. We'll see where it takes us."
