The Detroit Lions have signed free agent cornerback Nathan Vasher, reports Dave Birkett of the Detroit Free Press.

Terms were not disclosed, and the Lions will need to make a corresponding transaction to add Vasher to the 53-man roster.

A fourth-round pick (110th overall) out of Texas by the Chicago Bears in 2004, Vasher (5-10, 183) started 46 of 73 games for the Bears, totaling 164 tackles, 1 quarterback sack, and 19 interceptions during his six seasons in Chicago.

Vasher set a career-high with 8 interceptions in 2005, earning Pro Bowl and All-Pro honors after the season. After missing considerable time due to injuries in 2007 and 2008, Vasher started two of 15 games last season, totaling 15 tackles and an interception.

The Bears released Vasher on March 17, and he was signed by the San Diego Chargers, where he made 9 tackles and grabbed an interception before being released on September 4.
