The Bills reached an injury settlement with veteran linebacker Sam Barrington and released him from IR, a source tells Tom Pelissero of USA Today (on Twitter). Barrington should be healthy in a couple weeks and at that point he’ll be free to sign with another club. 
Barrington was one of ~30 players left off the roster by the Bills on Saturday as they trimmed down to a 53-man squad. The linebacker spent the first years of his career with the Packers before bouncing around the league last year. He appeared in 22 games (eight starts) while with Green Bay, but it’s fair to wonder if he’ll get another chance to see legitimate playing time after such a forgettable season.
Before signing with Buffalo, the only mention we heard of his name was a May workout for the Jaguars.
