Broncos center Dan Koppen suffered a torn left ACL in practice on Sunday, an injury that will end his season and possibly his career.
Koppen, 33, re-signed with the Broncos a month ago after J.D. Walton suffered a setback in his comeback from ankle surgery. Koppen filled in for Walton last season, starting 12 games.
The 11-year veteran, who played his first nine seasons with the Patriots, was caught in a pile early in the workout and was carted off the field and taken for an MRI, which revealed the season-ending injury.
Manny Ramirez, who took most of the snaps at center during Denver’s offseason practices, stepped in for Koppen, whose teams have gone 108-28 in games he has started.
‘‘You never like to see players get injured, particularly severely injured,’’ said coach John Fox. “But you understand when you do this long enough, whether you’re a player or a coach, that this happens. You know, you get them back ready. And you’ve got some guys that have worked hard off of injuries last year and it will be no different this year.’’
Koppen’s injury is the latest setback to Peyton Manning’s patched-up line.
Left guard Zane Beadles was the only starting lineman to come out of last season unscathed. All-Pro left tackle Ryan Clady has been limited since signing a $57.5 million contract earlier this month as he recovers from right shoulder surgery. Tackle Orlando Franklin (toe, shoulder) and guard Chris Kuper (ankle) are also coming off surgeries.
Pitta, Maclin done
As anticipated, Ravens tight end Dennis Pitta and Eagles wide receiver Jeremy Maclin will miss the season because of injuries.
Pitta had hip surgery Saturday night, just hours after colliding with safety James Ihedigbo going for a pass in the back of the end zone. The Ravens signed Visanthe Shiancoe, a 33-year-old free agent tight end who played in four games last season with the Patriots.
Maclin tore the ACL in his right knee during Saturday’s practice, and confirmed Sunday he’ll likely be out for the season. He is scheduled to have surgery Tuesday.
Ryan OK with sharing
Rex Ryan shrugged off comments made by Jets general manager John Idzik on Saturday that the decision on who will be the team’s starting quarterback will be a “collaborative one.” Incumbent Mark Sanchez and second-round pick Geno Smith are competing for the job. ‘‘I think you guys are making a mountain out of a molehill, to be honest with you,’’ Ryan said. ‘‘Ever since I’ve been here, and this is my fifth year here, not one decision has ever been made by one man. There’s a lot of teams in this league where the head coach does not have the final say on who makes the 53-man roster.’’ . . . The stress of coping with life led Will Hill to use marijuana, the Giants reserve safety said in his first comments after being hit by the NFL with a four-game suspension. Hill, who grew up in New Jersey, said he dealt with a lot of stress growing up, and just as much now. ‘‘It’s from family members, everyone reaching their hand out thinking I’m an ATM, and people who think you owe them something. How do you deal with those situations? I really can’t so I dealt with it the best way I knew how.’’ . . . Six-time Pro Bowl quarterback Donovan McNabb will officially retire a member of the Eagles on Monday. McNabb, who played 11 of his 13 seasons with the Eagles, hasn’t played in the NFL since 2011.
