Brown, who was signed Monday, could start Sunday against the Browns as DuJuan Harris was released Tuesday.
The move was a bit of a surprise, considering Brown is the only running back left on the roster besides Fred Jackson. And coach Pete Carroll said Monday that Jackson would remain in his third-down role. Fullback Derrick Coleman played running back in college and could get carries. Brown was on the Seattle roster earlier this season but never active. He has not played in a game this season. But unless the Seahawks make another move this week, Brown looks to get the bulk of the RB carries.
