The team's summer of sludge continued Sunday when starting center Dan Koppentore the anterior cruciate ligament in his left knee during training-camp practice. His season, and possibly career, is over. Koppen, you'll remember, was brought back to Denver last month after starting center J.D. Walton suffered a season-ending setback with an ankle injury.
Center is the biggest area of concern along Denver's offensive line, but it's not the only one. Left tackle Ryan Clady has been limited in practice as he comes back from shoulder surgery. Right tackle Orlando Franklin is working his way back from surgery on his toe and shoulder. Guard Chris Kuper isn't practicing as he recovers from ankle surgery.
That's an awful lot of uncertainty for a line with a massive responsibility: Keeping Peyton Manning off his back.
Some other plotlines from the day that was in the NFL ...
And then there were two ...
Jonathan Cooper and the Arizona Cardinals settled their differences Sunday. The seventh overall draft pick agreed to a four-year, 14.55 million contract, fully guaranteed with offset language. With Cooper under contract, Dee Milliner (New York Jets) and Chance Warmack (Tennessee Titans) are the only remaining holdouts among the first-round picks.
Rex in the spin zone
"I think the big thing is, you guys are making a mountain out of a molehill, to be honest with you," Ryan said. "Because ever since I've been here -- this is my fifth year here -- not one decision has been made by one man. Not one decision. It's always a group effort on what is best for this team."
It's sad seeing Rex like this. Where's the fire? The swagger? We miss that guy, not this limping dog in need of mercy.
