The future Hall of Fame quarterback was seen not wearing pads and was kept from throwing. There was speculation that Manning suffered an arm injury in the Broncos' first loss of the season, Sunday night in Indianapolis.

After Manning was beat up by former teammate Robert Mathis and the Colts' fast and physical defense, there wasn't quite the same zip on his passes as he tried to lead Denver on a big second-half comeback. In the post-game press conference at Lucas Oil Field, Manning admitted that some of this throws were "wobbly," but not at a percentage that was out of the ordinary.

Everything that happens with the 37-year-old signal caller regarding his health, even as little as a tweaked ankle, will get such attention. He's just two years removed from an entire season lost to a neck injury.


BROWNS BENCH WEEDEN


The Cleveland Browns are changing quarterbacks again.

This time, backup Jason Campbell is getting the start over Brandon Weeden Sunday against Kansas City. The same Jason Campbell who was passed by third-stringer Brian Hoyer before he sustained a season-sending knee injury.

Head coach Rob Chudzinski announced the decision on Campbell on Wednesday morning, although he told reporters that he had decided on Monday, a day after Cleveland lost its second straight game, 31-13 at Green Bay. It’s the third quarterback change Chudzinski has made involving all three quarterbacks on the roster.

"I'm committed to doing whatever gives us the best chance to win,’’ Chudzinski told reporters. “From a game plan standpoint, I like the things that Jason Campbell brings to the table.''

That appears to be a radical departure from the opinion of him the coach revealed through his playing choices all year.

Campbell began the season, his first with the Browns, as the second-stringer behind Weeden, and played at the end of their Week 2 loss in Baltimore after Weeden sprained his thumb. But the Browns went with third-stringer Hoyer to fill in for Weeden, and Hoyer started the next three games, winning the first two and suffering a season-ending torn ACL in a win the next week over Buffalo.

Weeden returned for the next two starts, both losses, dropping him to 0-4 as a starter this season. The future of last season’s first-round pick, who has started 19 games, is cloudy at best, and destined to continue on another team at worst. Weeden’s 66.5 passer rating is 31st in the NFL, above only the Vikings’ duo of Christian Ponder and Josh Freeman.

Campbell, 31, is on his fourth team in nine seasons; the first five were with Washington, before he was let go after Mike Shanahan was hired as head coach. He started for the Oakland Raiders in 2011, but played six games before suffering a season-ending broken collarbone.


FREEMAN CONCUSSED


The Minnesota Vikings have announced that quarterback Josh Freeman suffered a concussion in Monday night's Week 7 road loss to the New York Giants. Coach Leslie Frazier said if Freeman isn't ready to go in Week 8, Christian Ponder will start in Sunday night's home game against the Green Bay Packers.

"We have to move forward as if he is not playing on Sunday night," Frazier also said of Freeman during his Wednesday press conference.

Freeman struggled mightily in his first start for the Vikings, completing just 20 of 53 pass attempts for only 190 yards and an interception as the team failed to score an offensive touchdown in a 23-7 defeat. Although he was sacked only once, Freeman was hit several times by the Giants, who brought consistent pressure on him.

Ponder is looking at a chance to regain the starting job after not playing since Week 3 when the Vikings fell to 0-3 in a home loss to Cleveland. While Ponder was battling battered ribs, backup Matt Cassel started two games, going 1-1 against Pittsburgh and Carolina.

When Ponder played at home vs. Green Bay last season, the Vikings got running back Adrian Peterson past the 2,000-yard rushing mark and won their season finale to earn a wild-card playoff rematch with the Packers. He couldn't play in that second game, however, as the team struggled with then backup Joe Webb (now a wide receiver) at Lambeau Field.


SPILLER COULD SIT


Buffalo Bills coach Doug Marrone is uncertain whether running back C.J. Spiller will play at New Orleans on Sunday.

Marrone on Wednesday says he's considering sitting Spiller to give his sore left ankle time to heal. He added a decision won't be made until later this week.

Spiller hasn't missed a game, but his playing time and production have been limited since he was hurt against Baltimore on Sept. 29.
