Collins’ Green Bay career ended because of a neck injury suffered in the club’s second regular season game of 2011. Collins, who underwent vertebrae fusion surgery, was released by Green Bay in April 2012. He has not appeared in an NFL game since.
Earlier this year, Collins had indicated he was willing to consider a return to football.
Collins’ ball skills were a major strength. A three-time Pro Bowler, Collins picked off 21 passes in regular season play for Green Bay from 2005 through 2011, and he scored the Packers’ second touchdown in their Super Bowl XLV victory over Pittsburgh on an interception return.
In his statement Tuesday, Collins thanked his “family, friends, and the Packer Nation for the love and support.”
