UCLA has suspended receiver Josh Smith and F-back Morrell Presley for the Oct. 21 game at Oregon for violating team rules.
UCLA coach Rick Neuheisel announced the suspensions Tuesday before the start of the Bruins' bye week practices.
UCLA didn't specify the exact reason for the suspensions, citing student privacy laws.
Smith is the Bruins' top kick returner, averaging 27.4 yards on 14 kickoff returns. He also caught three passes in UCLA's first six games.
Presley's position is a combination of fullback and tight end. He also has caught three passes this season while starting all six games.
UCLA lost 35-7 at California last weekend to drop to 3-3 in Neuheisel's third season.
