49ers activate Glenn Dorsey, place Ian Williams on injured reserve

The San Francisco 49ers made a roster move Monday afternoon, activating Glenn Dorsey to the 53-man roster. The team made room for Dorsey by moving Ian Williams to the injured reserve list. Dorsey was previously on the injured reserve list, with a return designation while he rehabbed a torn biceps muscle. Williams suffered a fractured fibula and will sit out the remainder of the season.

The 49ers face Washington this weekend, and will have to contend with a passing game that includes DeSean Jackson, Pierre Garcon and Jordan Reed. While they can imposing presences in the passing game, Alfred Morris and the run game are what will keep Washington in this game. Having another option on the defensive line will be a big help.

Quinton Dial is likely to get the start at nose tackle, but we could see some kind of rotation along the line. Dorsey played nose tackle last season after Williams broke his ankle, but he can play all along the line. Tony Jerod-Eddie is the primary backup behind Justin Smith and Ray McDonald, with Tank Carradine starting to get some work there. Tank got 12 snaps this past week, after 5 the week before. It will be interesting to see how the activation of Dorsey impacts Tank's playing time.
