When Peyton Manning finally opened up about his foot injury earlier this month, the Broncos quarterback confirmed that he had been dealing with a partial tear in his plantar fascia "for quite some time."

The original belief was that Manning's foot problem started after he got injured against the Colts on Nov. 8. However, Manning never confirmed that.

In an interview on Dec. 2, the Broncos quarterback was evasive when asked about when exactly his injury occurred, calling timelines "irrelevant."

"I'd been having some symptoms that I've been dealing with," Manning said. "It's been going on for a little bit of time. Timelines and all that are kind of irrelevant. It bothers me now."

It's possible that Manning was evasive because he didn't want to reveal something that his dad ended up revealing this week: Peyton's been playing injured all season.

During an interview with WDSU-TV in New Orleans, Archie Manning revealed that Peyton has been dealing with a foot injury since at least August.

"He's really had this foot problem that's been going on for five or six months," Archie Manning said on Thursday.

That one statement raises a lot of questions: How serious was the injury? Did Peyton tell the Broncos coaching staff? Should he have been listed on Denver's weekly injury reports?

For the most part, Peyton has struggled whenever he's been on the field this season and if he's been dealing with a foot injury since August, that might explain some of his struggles. Also, Manning might have been afraid to reveal the extent of his injury because that could've given coach Gary Kubiak an excuse to start Brock Osweiler as early as Week 1.

Don't look for Peyton to call it quits anytime soon, though. Archie says that Peyton wants to come back this season and help the Broncos make a playoff run.

"He's not going to think about retirement right now," Archie said. "He's trying to get well. He wants to get well. He's got a team there that's in a playoff run he wants to help. If he gets back on the field, he wants to be ready."

Peyton's been rehabbing his foot for a little more than a month now. The Broncos quarterback hasn't played in a game since Nov. 15.

As for rumors that Peyton might play in 2016, the Broncos quarterback isn't looking far ahead yet, according to Archie.

"Peyton's got plenty of sense, so when everything's done at the end of the year he'll sit down and make a decision," Archie said. "Whatever he does, Peyton will attack it. If he steps down, he'll find something else and go after it. If he wants to play some more, he’ll go after it."
