Tony Gonzalez acknowledged that Atlanta's playoff loss to Green Bay on Saturday may have been his final NFL game. "It's always a possibility," Gonzalez said of retirement. "Year 15 is a long time." Gonzalez is now 0-4 in the postseason during his lengthy career. "I feel just as down just as devastated as I did last time," Gonzalez said. "It doesn't make a difference that it's towards the end of my career. It's in my mind, don't get me wrong, but they all hurt."
