The dogged determination that helped transform Rod Smith from an unknown and undrafted wide receiver out of Missouri Southern into a Pro Bowler and a two-time Super Bowl champion might ultimately spell the end of his career. The 37-year-old Denver Broncos' co-captain revealed Friday that his surgically repaired left hip hurts more than ever and that a specialist in Los Angeles will resurface or replace the joint in January. "It has not healed," said Smith, who's been out all season. "It's not healing at all." "Honestly, I don't even like walking on it," he said. "It's that bad right now to me, and it's a matter of the hip socket has been bone-on-bone for a while. That's [difficult], especially trying to play pro football on it. And, honestly, I think I did for a while without knowing it was probably doing more damage to it than good."
