James Harrison will play for Steelers

PITTSBURGH -- Steelers Pro Bowl linebacker James Harrison is active and will play Sunday night against the New England Patriots.

Harrison was a late addition to the injury report after suffering back spasms on Saturday. He was listed as questionable.

Harrison leads Pittsburgh in both sacks (seven) and forced fumbles (four). He also has 40 tackles and an interception for Pittsburgh (6-2) this season.

The Steelers will be without two starters, however. Defensive end Brett Keisel (hamstring) and guard Chris Kemoeatu (knee, ankle) will both sit out Sunday night's game.
