Denver Broncos quarterback Peyton Missing did not practice with the team on Wednesday because of an ankle injury but is expected to play Sunday against the Washington Redskins.
Manning was on the field but did not wear pads or participate in drills. The Denver Post reported that Manning was receiving treatment on the ankle.
Also missing practice were wide receivers Eric Decker and Wes Welker, guard Chris Kuper, tackle Orlando Franklin, linebacker Shaun Phillips, cornerback Champ Bailey and tight end Joel Dreessen.
The Broncos (6-1) lost for the first time this season on Sunday night, falling 39-33 to the Colts in Manning's return to Indianapolis. Manning threw for three touchdowns and one interception while completing 29-of-49 passes for 386 yards.
Manning was hit repeatedly during the game and took one particularly hard shot from former teammate Robert Mathis on a safety.
---Michael Vick will start Sunday against the New York Giants, unless his injured left hamstring prevents the quarterback from reclaiming the No. 1 job with the Philadelphia Eagles.
Vick has missed the last two games because a hamstring injury. He was a full practice participant for the second straight day Wednesday and took most of the first-team reps, which would seem to indicate that he will start this weekend.
But coach Chip Kelly still isn't ready to etch that in stone. He said Vick still hasn't really tried to run hard, and he's not ready to say for sure that Vick will start.
Part of that is an attempt to keep the Giants guessing, even though Vick's backup, Nick Foles, is out because of a concussion, and rookie Matt Barkley threw three interceptions last week after replacing Foles.
But a bigger part is that Vick still hasn't completely recovered from his hamstring injury, and Kelly wants to make sure the 33-year-old quarterback isn't at risk of aggravating it further by playing.
It's unlikely that Foles, who completed only 11-of-29 passes in last week's loss to the Cowboys before he was injured, will be cleared in time to play Sunday.
So the only option the Eagles have if Vick doesn't go is Barkley.
The Eagles signed former University of Tulsa quarterback G.J. Kinne to their practice squad earlier this week. Kinne was with the Eagles during spring OTAs and training camp before being released.
If Vick and Foles both can't play, Barkley would start and Kinne would be promoted from the practice squad and back him up.
Foles' atrocious performance against the Cowboys pretty much eliminated his chances of taking the starting job from Vick. He played about as poorly as you can possibly play, missing wide-open receivers and averaged only 2.76 yards per pass before being injured when he was sacked by Cowboys defensive linemen George Selvie and Jarius Wynn.
---NFL hearing officer Ted Cottrell reduced the suspension of Washington Redskins safety Brandon Meriweather from two games to one.
Meriweather has been at the center of a number of repeated hits to the head this season, including hard stops of Brandon Marshall and Martellus Bennett, which prompted the NFL to suspend him for two games, NFL.com reported.
Meriweather was penalized twice in the Redskins' Week 7 win against the Chicago Bears for using his helmet to spear and hit Bears receivers Marshall and Bennett in the head and neck area.
Marshall publicly criticized Meriweather's play afterward, while Bennett told reporters he'd like to punch Meriweather in the face.
Because he is a repeat offender, Meriweather drew the unprecedented two-game suspension, but then appealed.
---The Washington Redskins re-signed free agent safety Jordan Pugh just a week after he was released. Terms of the deal were not disclosed.
Pugh played in 16 regular-season games and one playoff game in 2012 and 2013 before his release on Oct. 15 as part of the Redskins' push to upgrade their special teams. He has seen action in three games this season but does not have a tackle.
Re-signing Pugh reflects the Redskins' uncertainty at safety this week because of a one-game suspension that Brandon Meriweather faces and the status of Reed Doughty (concussion).
The 5-foot-11, 210-pound Pugh was drafted in the sixth round out of Texas A&M by the Carolina Panthers in 2010 and was cut before the start of the 2012 season. He then signed with the Redskins.
---Jason Campbell is in and Brandon Weeden is out as the Cleveland Browns' starting quarterback.
