Defensive tackle Tank Carradine, a rookie second-round pick, was activated from the San Francisco 49ers' non-football injury list and added to the team's active roster.
To clear room for Carradine, the 49ers waived linebacker Jermaine Cunningham.
Carradine, who is 6-foot-4, 273 pounds, tore his right anterior cruciate ligament last November while playing for Florida State, but the injury didn't prevent San Francisco from selecting him 40th overall last spring. He returned to practice Oct. 15.
"He's still coming along," coach Jim Harbaugh said. "He's getting the feel back playing 11-on-11 football, but it's coming."
A first-team All-ACC player as a senior, Carradine had 16.5 sacks, 21 tackles for loss, one forced fumble and one fumble recovery over his two seasons with Florida State. He previously played for Butler Community College in Kansas.
Cunningham signed with San Francisco on Oct. 1 but never made the game-day roster in his four weeks with the team.
