Broncos quarterback Peyton Manning throws on his own for first time in three weeks

Peyton Manning threw on his own for the first time in 3 1/2 weeks Wednesday, when more than a dozen Denver Broncos were either limited at practice or held out altogether.

Coach Gary Kubiak said Manning “did about a half hour of throwing” and some drill work inside the Pat Bowlen Fieldhouse with the strength and conditioning staff apart from the rest of the team.

The 39-year-old quarterback has been sidelined since Nov. 15 with a torn plantar fascia in his left foot, bruised ribs and a sore throwing shoulder.

Asked if he watched Manning’s workout, Kubiak said: “Yeah, I am definitely involved with them, whether it’s film or personally [going] over there depending on what’s going on that part of the day. We’ve got a good little process going on right now. We’ll stick to it throughout the course of the week.”

Manning has said he has no timetable for a possible return because doctors cannot tell him when he’ll be healthy again.

Brock Osweiler, 3-0 in Manning’s place, makes his fourth start Sunday when the Broncos (10-2) host the Oakland Raiders (5-7).

Manziel learns ‘hard lesson’

Cleveland Browns quarterback Johnny Manziel didn’t like being punished for partying. He didn’t agree with being benched and isn’t happy it cost him the spotlight of a Monday night game. But now that his punishment’s over, Manziel says he wants to make the most of his new chance to start.

And if he doesn’t behave, it may be Johnny Football’s last chance with the Browns.

Speaking to reporters for the first time since being demoted last month for off-field behavior, Manziel didn’t apologize for his actions, offered no promises and said he feels fortunate to be back in the starting lineup this week against San Francisco.

“I was forced to learn a hard lesson,” he said. “I had to learn the hard way and I’m lucky to be back in the position that I’m in and being the starter again, so I’m definitely not taking that lightly. That’s for sure.”

Browns Coach Mike Pettine punished Manziel after a video surfaced of the polarizing and popular quarterback holding a champagne bottle and rapping profane lyrics at a club in Austin, Texas. Manziel had promised the Browns he wouldn’t be a distraction during the team’s bye week and then became one on social media sites.

Manziel called the situation “a lapse in judgment” and said he learned his lesson.

“Obviously, there’s a way to conduct yourself that 31 other guys in the league do each and every week,” he said. “You have to follow that example and realize that this is a very prestigious situation that I’m in being a starting quarterback in the NFL, so I have to take pride in that and act accordingly.”

He had better. Pettine warned Wednesday that the team won’t stand any more off-field shenanigans. “It would be hard for me to sit here and say, ‘We have a zero-tolerance policy,’ ” Pettine said. “But if something were to occur, I could imagine that the repercussions would be harsh.”

McCoy won’t greet Kelly

Buffalo Bills running back LeSean McCoy had a blunt response to Philadelphia Eagles Coach Chip Kelly’s offer to shake hands on the field in Philadelphia on Sunday.

“Chip can’t shake ...,” McCoy said, using a profanity. “He can’t call me. He can’t shake my hand. There’s nothing he can do with me. ... It’s as simple as that.”

Nine months have passed since Kelly decided to part ways with the Eagles’ most dynamic offensive threat at the time, trading McCoy to Buffalo in exchange for linebacker Kiko Alonso. And McCoy, in preparing to face his former team for the first time, made it abundantly clear that he still holds a grudge by how abruptly his six-year stint in Philadelphia ended.

McCoy, who previously suggested Kelly’s move was racially motivated, insisted he doesn’t dislike his former coach. “I have nothing against him,” he said. “No hatred. We’re not enemies.”
