The San Francisco 49ers have activated rookie defensive tackle Tank Carradine off the team’s Reserve/NFI list. In a corresponding move, the 49ers released linebacker Jermaine Cunningham to make room for Carradine on the 53-man roster. Cunningham was signed by the team on Oct. 1. Carradine figures to be one of many late-season additions to San Francisco’s roster. Carradine, the No. 40 overall selection in the 2013 NFL Draft out of Florida State, had been on the NFI list since Aug. 27 and could make his NFL debut as soon as Nov. 10 at home against the Carolina Panthers. The 6-foot-4, 273-pound defensive tackle suffered a torn ACL last November, ending a senior season that saw him total 11 sacks in 11 starts. Carradine returned to practice two weeks ago on Oct. 15 and is now the eighth rookie and sixth 2013 draft selection on San Francisco's active roster. The athletic defensive lineman began his college career at Butler Community College in Kansas and then went on to star at Florida State. Carradine appeared in 25 games at FSU and made 11 starts, totaling 118 tackles, 16.5 sacks and 21 tackles-for-loss in two seasons. He was a first-team All-ACC selection in 2012.
