Bulger, who was due $8.5 million next season, started eight games last season, but was sidelined the last six with a fractured left shin bone, finishing the year on injured reserve. Rookie Keith Null started the last four games, and veteran Kyle Boller also made four starts.
In nine seasons, all with the Rams, he completed 62.1 percent of his passes for 22,814 yards, with 122 touchdowns and 93 interceptions. He signed a six-year, $65 million contract in training camp in 2007.
