BOULDER, Colo. (AP) - Bryan Stoltenberg, an All-America offensive lineman for the Colorado Buffaloes, has died. He was 40.

Stoltenberg recently underwent several surgeries after being in a car accident last month, the school said on its website. He died Friday at his home in Sugarland, Texas.

A two-time, first-team All-Big Eight center in the mid-1990s, Stoltenberg was picked by San Diego in the sixth round of the 1996 draft. He played 50 games for the Chargers, New York Giants and Carolina Panthers.

Stoltenberg suited up for three seasons under Bill McCartney and another for Rick Neuheisel. With Stoltenberg helping to pave the way, Rashaan Salaam rushed for a school-record 2,055 yards in 1994 and won the Heisman Trophy.

Services are still pending. Stoltenberg is survived by his wife, Laura, and three sons.
