UCLA outside linebacker Rocen Keeton and tight end Corwin Anthony each underwent arthroscopic surgery on their right knees Wednesday.
Keeton, a senior, had a torn cartilage, but no ligament damage. It’s estimated he’ll be inactive from three to six weeks.
Anthony, a senior who alternates with Randy Austin, is expected to be sidelined from two to six weeks.
Earlier, UCLA lost senior flanker Scott Miller with a broken collarbone. He’s not expected to be ready to play until the Washington State game on Sept. 29 in Pullman, Wash.
The Bruins will open the season on Sept. 8 against Oklahoma at the Rose Bowl.
