LOS ANGELES -- UCLA linebacker Isaiah Bowens tore his ACL on Thursday in practice and will undergo surgery in the next couple of weeks, coach Jim Mora said Saturday.

Bowens, a rising redshirt sophomore out of Bishop Amat High in La Puente, was competing for time at the middle linebacker spot and was the team's first-string middle linebacker after Patrick Larimore suffered a concussion earlier in the week, but he will now miss next season.

"That’s a bad deal," Mora said. "That’s a big loss for us and I feel bad for the kid. He’s doing well and working hard and you just hate for that to happen. It’s a part of the game, but it’s a part of the game you just don’t like."

Bowens suffered the injury during a play late in team drills Thursday. He crumpled to the ground after taking a helmet to his knee and then hobbled off the field.

"I couldn’t even watch the video of it," Mora said. "He took a shot on that thing."

In other injury news, linebacker Eric Kendricks was limited because of a shoulder injury, running back Malcolm Jones sat out the last few periods after taking a blow to the head and cornerback Anthony Jefferson also sat out the last portio of practice after getting hit in the back.
