ENGLEWOOD, Colo. —Tight end Jake Butt is being evaluated for a left knee injury he suffered during Thursday's practice, Head Coach Vance Joseph announced.
Butt was listed as limited on Thursday's practice report.
Cornerback Tramaine Brock missed Thursday's practice after participating Wednesday, but Joseph said Brock did not suffer a new injury.
"He just wasn't up to going full speed today, so we thought [we would] be smart with him one more day," Joseph said. "[It] should help him get healthy."
Safety Dymonte Thomas, linebacker Brandon Marshall and cornerback Adam Jones were all limited.
Thomas and Jones have now practiced in some capacity during both sessions since missing Sunday's game.
Marshall did not practice Wednesday, but returned to the field on Thursday.
Joseph said quarterback Case Keenum, who missed a practice last week with knee soreness, is continuing to improve.
"He's doing fine," Joseph said. "I thought Case came out of the game fairly healthy. He had no swelling, he had no issues. So he should obviously feel better this week."
