METAIRIE, La. — What might have been former Heisman Trophy winner Mark Ingram's best season as a pro is over with four games left on the Saints' season.
New Orleans placed Ingram, its most productive running back, on injured reserve Wednesday, ending his season after 12 games. The Saints visit the Bucs on Sunday in an NFC South showdown.
Ingram's recent shoulder injury got worse, the Associated Press reported.
Ingram had been on the team's injury report with shoulder soreness last week but played all of Sunday's 41-38 loss to the unbeaten Panthers. He also scored his sixth rushing touchdown of the season with a little more than five minutes left in the fourth quarter.
Ingram, selected for the Pro Bowl as an alternate last season, has been the team's leader in yards from scrimmage this season with 1,174, including 769 yards rushing.
"Obviously, he has been tremendous and been extremely reliable in all phases of the offense," quarterback Drew Brees said of Ingram. "Over the last two years especially he has kind of come into his own. I would consider him one of the top backs in the league, all-purpose, can do everything and just a great guy to be around and great locker room guy. I don't know if there is a guy more liked than him."
New Orleans activated fullback Austin Johnson from the practice squad.
MANZIEL DEFIANT: 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 wants to make the most of his new chance to start.
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 the 49ers.
"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."
And if there's a reoccurrence? "If something were to occur, I imagine the repercussions would be harsh," coach Mike Pettine said.
NO BACKSTABBING: Eagles coach Chip Kelly said running back DeMarco Murray is unhappy with the carries he got in Sunday's upset win of the Patriots but didn't undercut anyone by speaking with team owner Jeffrey Lurie. Kelly rebutted rumors that Murray sought out Lurie, saying the NFL's rushing leader from last season simply sat next to Lurie on the flight home from Massachusetts.
MCCOY STILL BITTER: Don't expect LeSean McCoy to be shaking Eagles coach Chip Kelly's hand when the Bills running back travels to Philadelphia to face his former team for the first time Sunday. "Chip can't shake" anything, McCoy said, using a profanity. Kelly abruptly ended McCoy's career in Philadelphia by trading him to Buffalo last spring.
MANNING THROWS: Broncos quarterback Peyton Manning threw indoors on his own for the first time in 31/2 weeks. Manning has been out since Nov. 15 with a torn plantar fascia in his left foot, sore ribs and a sore throwing shoulder.
PROGRESS FOR LUCK: Colts quarterback Andrew Luck ran with his teammates, another step in his recovery from a lacerated kidney and partially torn abdominal muscle. He hasn't practiced since suffering the injuries Nov. 8.
BEARS: Receiver Kevin White participated in 11-on-11 drills, another step as the rookie works his way back from a left shin injury that has sidelined him all season.
BENGALS: Tight end Tyler Eifert was on the practice field for the first time since he suffered a stinger in Week 12 and is on track to return this week.
BRONCOS: The team bolstered its depth at safety by signing Shiloh Keo, who played 42 games with the Texans and is familiar with defensive coordinator Wade Phillips' schemes.
CHARGERS: Guard D.J. Fluker said his most recent concussion was the scariest of the four he has had in his three seasons. Fluker, hurt late in a loss to the Chiefs on Nov. 22, said his entire body tingled and his focus went in and out for a few plays.
JETS: Former Bucs cornerback Darrelle Revis rejoined his teammates, attending practice for the first time since suffering a concussion Nov. 22.
RAMS: Defensive end Robert Quinn is set for back surgery and safety T.J. McDonald is headed for a shoulder procedure, knocking both out for the season.
VIKINGS: Quarterback Teddy Bridgewater brushed off Seahawks linebacker Bruce Irvin's comment that he looked "scared" last weekend. "I'm going to make sure I remember those words," Bridgewater said. "But I can't lock in and pay too much attention to that."
