ORCHARD PARK, N.Y. (AP) -- The Buffalo Bills have signed free agent defensive lineman Alex Carrington.
Carrington returns to the team that selected him in the third round of the 2010 draft. Carrington played for the Bills from 2010-13 before joining the St. Louis Rams in 2014.
Carrington has 54 tackles and four sacks in five seasons, mostly as a backup. He earned a starting job with the Bills in 2013 before a torn quadriceps ended his season after three games.
The signing gives the Bills added depth and experience on the defensive line as the team transitions to a 3-4 scheme under coach Rex Ryan.
