Arizona football linebacker Jake Fischer will undergo surgery this week to repair a torn ACL, according to the Arizona Daily Star.

Fischer, a junior, hurt the knee in Saturday's spring game and was helped off the field, visibly hurting to the point where he could put little, if any, pressure on the knee.

Via the Daily Star:

The UA announced the pending surgery this morning, four days after Fischer suffered an injury during the final minutes of the team’s annual spring game. Fischer will undergo surgery some time in the next week,  and could be out as long as seven months.

The injury is a huge hit to the Wildcats, who already had poor depth at the linebacker position. R.J. Young decided to transfer during the offseason, leaving five LBs on the roster. Three of those — Rob Hankins, Hank Hobson and Domonique Petties — will be freshmen next season.

Returning are seniors Paul Vassallo and Derek Earls, but Fischer leaves a solid 58 tackles, 7.5 for loss, off of the field. He put up those numbers his sophomore season and proved to be the fastest of the three starters.

Still, Arizona will again play a lot of nickel an dime packages, though the injury to safety Adam Hall makes Fischer's injury yet another major set-back before the fall semester even hits.

How worried are you about Arizona's injuries stacking up on both offense and defense?
