The Washington Redskins have released running back Shaun Alexander after four games and 11 carries with the team.
The 31-year-old former league MVP had provided insurance while injuries prevented Clinton Portis and Ladell Betts from practicing.
Portis and Betts continue to battle through injuries, but the Redskins apparently felt they needed Alexander's roster spot to help with depth on the defensive line.
The Redskins replaced Alexander on the roster by signing defensive tackle Ryan Boschetti. Defensive end Andre Carter and defensive tackle Kedric Golston both suffered foot injuries, and defensive tackle Cornelius Griffin hurt his shoulder in Sunday's 20-17 victory over the Seattle Seahawks.
