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. The Bills did not select any defensive linemen in the draft.
Carrington also is a presence on special teams. He set a Bills record in 2012 by blocking six kicks (four field goals, two extra points).
The Bills also signed 13 undrafted free agents Monday: OT Jermaine Barton (Illinois State), TE Clay Burton (Florida), OT Tyson Chandler (N.C. State), WR Andre Davis (South Florida), DT Justin Hamilton (Louisiana-Lafayette), LB Andrew Hudson (Washington), DE BJ Larsen (Utah State), CB Merrill Noel (Wake Forest), DE Cedric Reed (Texas), LB AJ Tarpley (Stanford), CB Cam Thomas (Western Kentucky), P Spencer Roth (Baylor) and DE Erik Williams (Bethune Cookman).
