Former Green Bay Packers cornerback Al Harris has cleared waivers, freeing the 13-year veteran to sign with any team, according to a league source.
The 35-year-old Harris was released by the Packers on Monday as he was attempting to return to the field after a serious knee injury.
Harris is nearly a year removed from a season-ending left knee injury last November. He began this season on the team's physically unable-to-perform list and returned to practice Oct. 19, giving the Packers a three-week timeline to decide his future.
"I think Al Harris will definitely play again in the National Football League," McCarthy said.
"This is not a physical decision," McCarthy said. "This is a big-picture roster decision."
Harris started all 102 games he played for the Packers after he was acquired from Philadelphia in 2003. He had 14 interceptions and 108 passes defensed during his time in Green Bay.
