According to reports, the Bills dumped Thad Lewis just a day after severing ties with Dennis Dixon and planned to sign career backup quarterback Jordan Palmer.
The Chicago Bears released Palmer during the weekend after deciding to go with Jimmy Clausen. Palmer has not thrown a pass in the NFL since 2010 and only 15 in his career.
That leaves Jeff Tuel as the Bills' probable backup to Manuel. Tuel played in two games last season and completed 26 of 59 passes (44.1 percent) for 309 yards and one touchdown with three interceptions.
Lewis started five games for the Bills last season and had some decent moments, completing 59.2 percent of his passes for 1,092 yards and four touchdowns with three interceptions. But the Bills were unhappy with their quarterback play during the offseason and preseason, particularly in the 27-14 exhibition loss to the Tampa Bay Buccaneers on Saturday.
