Tyler Evans has torn ACL

NORMAN, Okla. -- Oklahoma already has lost two offensive linemen to injury through just four spring practices.

Days after starting center Gabe Ikard broke his snapping hand, Sooners coach Bob Stoops revealed Thursday that senior guard Tyler Evans re-tore the ACL in his right knee, effectively ending his 2013 season if not his college career.

Evans will undergo surgery to repair the torn ligament, Stoops said.

Evans, who had 29 career starts going into the 2012 season, first tore the ligament on the first day of practice last August.

After receiving a medical hardship and another year of eligibility, Evans spent the last several months rehabbing the knee and was hoping to rejoin the team in contact drills later this spring.

Stoops said it was doubtful that Oklahoma would pursue a second hardship for Evans.
