The San Francisco 49ers activated rookie defensive lineman Tank Carradine from the reserve-non-football injury list.
The 49ers cut outside linebacker Jermaine Cunningham.
A second-round draft pick from Florida State, Carradine tore his anterior cruciate ligament last November against the University of Florida. He had 11 sacks as a senior last season.
For his career, Carradine had 118 tackles, 16 1/2 sacks and 21 tackles for-loss in two seasons.
