BERKELEY, Calif. -- Former California and NFL star Andre Carter has returned to the Golden Bears' football program as a student assistant coach.

Head coach Sonny Dykes said Thursday that Carter will assist with the team's defensive line.

Carter enrolled as an undergraduate at Cal earlier this year to pursue his bachelor's degree in American studies.

Carter played 13 years in the NFL after being drafted seventh overall by San Francisco in 2001. He also played with Washington, New England and Oakland.

Carter won the Morris Trophy as the top lineman in the Pac-10 in his senior season at Cal in 2000 and is the school's career sacks leader with 31.
