ENGLEWOOD, Colo. – Broncos center Dan Koppen is out for the season after tearing his left ACL on Sunday in 9-on-7 drills, less than six weeks after rejoining Denver following J.D. Waltons setback in his comeback from ankle surgery.
Koppen, an 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.
Manny Ramirez, who took most of the snaps at center during Denvers offseason practices, stepped in for Koppen.
Later in the day, the Broncos signed free-agent center Steve Vallos, pending a physical.
Left guard Zane Beadles was the only starting lineman to come out of last season unscathed.
Jags guard practices after totaling car
Jacksonville guard Drew Nowak is back at practice, a day after totaling his car while driving to the team hotel.
Nowak, a second-year player who missed all of last season with a foot injury, crashed his 2001 Mercedes-Benz a couple of miles from EverBank Field. Another driver ran a red light, smashed into the passengers side of Nowaks car and plowed him onto a curb.
Cardinals QB coach back after close call
Less than two months ago, during an offseason practice at the Arizona facility, quarterbacks coach Freddie Kitchens felt two pops in his chest.
Then his vision turned blurry and a leg felt numb.
They were the early symptoms of an often-fatal illness called aortic dissection.
But the 38-year-old coach is back at work at training camp, feeling a little tired but otherwise healthy.
In other news, the Cardinals reached a contract agreement with first-round draft pick Jonathan Cooper.
