The New York Giants signed defensive back Terrell Thomas on Monday.
Thomas, who has battled injuries throughout his career, has not played in a regular-season game since Jan. 2, 2011, the finale of the 2010 season. Thomas missed 2011 and 2012 after tearing the anterior cruciate ligament in his right knee.
It is possible that Thomas, a cornerback, will switch to safety next season, a move that might be easier on his knees.
Thomas was a second-round draft choice by New York in 2008 out of Southern Cal, and started every game in 2009 and 2010. He led the Giants in tackles, interceptions and passes defensed each season.
The Giants went 9-7 last season, but failed to make the playoffs. The defense allowed 344 points.
