ENGLEWOOD, Colo. -- Peyton Manning won't suit up against the Chicago Bears on Sunday. Broncos coach Gary Kubiak is going with backup Brock Osweiler as he tries to get his 39-year-old quarterback healthy.

Kubiak said he met with Manning on Monday morning and told him of his decision -- which Manning didn't like.

Said Kubiak: "I've never met a player who agreed to that."

Manning had the worst game of his career Sunday in Denver's 29-13 loss to Kansas City. He completed 5 of 20 passes for 35 yards with four interceptions and had a 0.0 passer rating.

Manning is dealing with a variety of ailments, including a torn plantar fascia in his foot, a person familiar with the situation told The Associated Press on Monday.

It's uncertain how long -- if at all -- the nagging injury would sideline Manning. He was benched for the first time in his career Sunday after throwing four interceptions in Denver's 29-13 loss to Kansas City.

Manning has been dealing with the sore foot for a while. It was especially bothersome after playing on the artificial turf in Denver's 27-24 loss at Indianapolis on Nov. 8, and Manning was extremely limited in his practice last week.

On Saturday, he showed up with a new ailment: sore ribs. In light of that, coach Gary Kubiak said he regretted starting Manning against the Chiefs but had done so out of deference to the five-time MVP.

Kubiak didn't replace Manning until late in the third quarter after Manning had been picked off four times, completed just 5 of 20 passes for 35 yards and posted a career-worst 0.0 passer rating.

Longtime backup Brock Osweiler finished up.
