The Bills cut starting left tackle Langston Walker on Tuesday.
Walker will be replaced in the starting lineup by second-year player Demetrius Bell, assuming his back heals up prior to Monday's season opener.
Bell, a seventh-round pick in 2008, never got into a game last season.
Walker's release saves the Bills $3 million in cash. He will still count $4.5 million against the salary cap due to past bonus payments that he received.
