Bulluck suffered a torn ACL in the victory over the Dolphins on Sunday, while Thornton will miss the remainder of the year with a pectoral injury.
At 32, it's going to be hard for Bulluck to return to his previous level of performance after a torn ACL. Matt Lepsis came back from an injury at 32 to make it through 16 more starts, but that was it. Rob Morris tore his ACL at 32 in 2007 and retired. The list of all post-30 ACL tears for linebackers isn't pretty, either, with the majority of guys never seeing another NFL snap. Bulluck will probably make it back, but it's hard to imagine he'll approach his previous levels of performance.
