The San Francisco 49ers activated defensive-lineman Tank Carradine (6’4, 270lbs) off injured/reserve one day before they take on the Seattle Seahawks. The team released veteran linebacker Ray-Ray Armstrong (6’3, 220lbs) to make room on the 53-man roster.

Carradine was placed on IR back in September due to a high-ankle sprain he suffered against the Los Angeles Rams. Prior to being shelved, the former-FSU Seminole had started two of three games of the season — registering seven tackles and one sack.

The 49ers can use all the reinforcements they can get ahead of Sunday’s match-up at home against division-rival Seattle Seahawks. SEA QB Russell Wilson has a knack of driving opposing players and coaches insane with his ability to extend and create plays outside of the pocket.

Linebacker Ray-Ray Armstrong had appeared in each of the 49ers ten games this season, starting five of them. He totaled 53 tackles, 2 interceptions, 1 sack, 1 forced fumble, and two passes defended.
