The Detroit Lions re-signed cornerback Alphonso Smith on Thursday in an effort to shore up a position that's presently depleted by injuries.

Smith was a 10-game starter for Detroit in 2010 and led the team with five interceptions that season, then compiled 27 tackles and three picks over 11 games (1 start) last year. He was released by the Lions during final cuts following this preseason.

Detroit entered the week with only Chris Houston and rookie Jonte Green as the club's healthy cornerbacks, with Jacob Lacey (concussion) and 2012 third-round pick Bill Bentley (shoulder) both injured during Sunday's 26-23 overtime win at Philadelphia.

To make room on the 53-man roster, the Lions released running back Keiland Williams. The third-year pro rushed for 195 yards and two touchdowns for Detroit last season, but had just two carries and two receptions over the first five games of 2012.
