ENGLEWOOD, Colo. - A person with knowledge of the results says Peyton Manning's MRI showed aggravation of his right ankle that is not expected to keep the Broncos quarterback out of next Sunday's game against Kansas City.

The person spoke to The Associated Press on the condition of anonymity because the team hasn't addressed the issue. Interim coach Jack Del Rio meets with the media Monday afternoon.

While Manning was throwing the final pass in a 28-20 win over the Chargers, San Diego lineman Corey Liuget hit the quarterback around the ankles. Manning was noticeably limping as he finished the game.

He had an MRI this morning.

Manning originally hurt both ankles last month.

The Denver Post had first reported the results of the MRI.

After Sunday's game, Manning said the time off during last week's bye helped "but I imagine I'll be pretty sore tomorrow."

Manning threw four touchdown passes to bring his season total to 33 - tied with Tom Brady for the most after nine games in NFL history.

With Chris Clark subbing for All-Pro left tackle Ryan Clady, who's on IR following a foot operation, Manning has been hit from his blindside and fumbled in Denver's last three games.

Those protection issues are a big concern with the unbeaten Kansas City Chiefs up next. The Chiefs lead the league with 36 sacks, including 11 by Justin Houston and 9 by Tamba Hali.

Manning missed some practice time before the Washington game two weeks ago and it's possible he'll be limited or sit out some workouts this week, too.
