Poll: Should Peyton Manning retire?

Peyton Manning is one of the all-time great NFL quarterbacks. But he did not look that way Sunday during the Denver Broncos' 24-13 playoff loss to the Indianapolis Colts and hasn't looked like his usual self in several weeks.

It could be age catching up with the 38-year-old Manning. And likely his health, as there are various reports out there about the severity of the thigh injury that was reported by the Broncos going into Sunday's game.

So after four NFL MVP awards, three Super Bowl appearances and one Lombardi Trophy, is it time for Manning to retire?

Manning himself was noncommittal after Sunday's game when asked if he would return for an 18th season.

"I guess I just can't give that simple answer," he said. "I'm processing it. I can't say that. I could not say that."

What do you think? Is it time for Manning to call it a career? Or does he still have a chance to recapture the magic he had just a year ago, when he set a record for passing yards in a season?
