UCLA defensive lineman Eddie Vanderdoes tore his anterior cruciate ligament in Saturday's win over Virginia and will miss the rest of the season, a source at the school told ESPN.com, confirming multiple reports.
The Bruins confirmed the injury Sunday night.
After the game, UCLA coach Jim Mora told reporters he thought the knee had "locked up on him."
Losing Vanderdoes is a significant blow to the Bruins defense, which boasted one of the strongest fronts in college football, with Vanderdoes alongside nose tackle Kenny Clark. Last year, Vanderdoes was an All-Pac-12 honorable mention after recording 50 tackles, including 5½ for a loss, and two sacks.
He led UCLA on Saturday with eight tackles, including two for a loss.
The No. 13 Bruins travel to UNLV on Saturday.
