When Nate Irving wretched his right knee , concern outweighed hope. The Broncos wanted to keep Irving available, but knew it might not work out. Friday, coach John Fox explained as the Broncos added linebacker Todd Davis to their practice squad.
“It was a consideration the whole time. It became more evident after swelling went down that was the best way to pursue it going forward,” Fox said of Irving, who suffered a partially torn medial collateral ligament. “We wish all the best in his rehab as he prepares for surgery.”
Davis, plucked off waivers from the New Orleans Saints, will join the Broncos in St. Louis.
The Broncos packed up quickly after practice, headed to the airport for a flight to St. Louis. Denver will not have running back Ronnie Hillman — he’s out two-to-four weeks with a sprained foot — and it appears unlikely that tight end Virgil Green will play. He did not participate in the team portion of practice as he recovers from his second bout with a calf injury.
St. Louis is hurting in the secondary. Cornerback Marcus Roberson (ankle) was ruled out for Sunday’s game. Linebacker Daren Bates (groin), defensive back Lamarcus Joyner (groin), wide receiver Damian Williams (hamstring) are listed all doubtful on Friday’s injury report.
