Former Jaguars, Lions and Giants CB Brian Witherspoon has retired from the NFL. Witherspoon appeared in 23 games across three seasons, serving mostly as a kick returner. Two torn ACLs led to his quick exit from the league.

Giants waived/injured CB Brian Witherspoon. Attempting to return after missing the entire 2011 season, Witherspoon re-injured his left ACL in the Giants' first spring practice on Wednesday. If the ACL is torn again, Witherspoon will have to sit out his second straight season.

Giants CB Brian Witherspoon re-injured his ACL in Wednesday's practice. Witherspoon had to be carted off the field in the team's first practice of OTAs. It's tough luck for a player who was likely facing an uphill battle to make the final roster.

Giants CB Brian Witherspoon announced Tuesday that he's out for the season with an ACL tear. He'll be placed on injured reserve later this week. Witherspoon has always been more of a kick returner than cornerback, but his injury highlights the Giants' lack of depth in the secondary after losing three corners earlier in camp.
