The San Francisco 49ers have added rookie defensive tackle Tank Carradine to their active roster.

The second-round Draft pick started the season on the non-football injury list after tearing his ACL during his final year in college.

Head coach Jim Harbaugh told reporters: "He's still coming along. He's getting the feel back from playing 11-on-11 football. But it's coming."

Carradine, who has been practising for the last two weeks, made 118 tackles and 16.5 sacks during his two seasons for Florida State Seminoles.
