Peyton Manning throws but not ready to return

ENGLEWOOD, Colo. -- Denver Broncos quarterback Peyton Manning isn't ready to play yet, but Wednesday morning he did have his most extensive throwing session since he was removed from the Broncos' Nov. 15 loss to the Kansas City Chiefs.

Manning was 5-of-20 passing in that game for 35 yards with four interceptions.

"He worked out briefly [Wednesday] morning," Broncos coach Gary Kubiak said. "[He] did about a half-hour throwing, went through some drill work and stuff. We're going day-to-day with that and see how he comes out of each day."

Manning threw with members of the Broncos' strength and conditioning staff inside the team's indoor practice facility while the rest of the team was in meetings. Manning is working back from a tear in the plantar fascia near his left heel.

Manning had the foot immobilized for two weeks -- just more than a week in a cast to go with a few days in a walking boot -- and was allowed to restart his rehab on Saturday. Manning also had a rehab session Monday and was given Tuesday as a day off from his work with the trainers before he threw Wednesday as part of his rehab work.

"We'll see how he comes out of each day," Kubiak said. "We'll just take it day to day. ... We've got a good little process going right now; we'll stick to it throughout the course of the week."

The Broncos, now 10-2, have won all three of Brock Osweiler's starts, including Sunday's 17-3 win over the San Diego Chargers. Osweiler has completed 61.3 percent of his passes with five touchdowns and three interceptions.

Kubiak has said Manning has done some conditioning work in recent weeks -- largely upper body -- and has done some minimal throwing as well. Wednesday's session was both the longest in duration and the first organized session since he had the cast and walking boot removed.

Manning said last week he had been bothered with plantar fasciitis for "some time" this season but that he suffered the tear in the Broncos' Nov. 8 loss in Indianapolis.
