Nine NFL seasons have taken a toll on Detroit Lions wide receiver Calvin Johnson's body.
His fingers are gnarled. He spends as much time in the training room as anyone on the team. And a lingering ankle injury forced him to miss large amounts of practice time this year, for the second straight season.
All that wear and tear has caused Johnson to contemplate his future. He has mentioned the subject of retirement to at least one former teammate.
Longtime Detroit radio host Terry Foster wrote in a column on The Ticket's website Tuesday that he thinks Johnson could walk away from the game, and several people who know the Pro Bowl receiver agree that it's not a far-fetched scenario.
