ENGLEWOOD, Colo. — The Broncos may be shorthanded in the secondary on Monday, as cornerback Tramaine Brock (thigh) was listed as doubtful on the team's final injury report before Denver's game against Kansas City.
Brock did not participate in practice on Thursday or Friday and was limited on Saturday.
He exited in the first half of last Sunday's game against the Ravens with a groin injury.
The Broncos also listed safety Dymonte Thomas (abdomen), cornerback Adam Jones (thigh) and linebacker Brandon Marshall (knee) as questionable. All three players were limited during Saturday's practice.
Tight end Jake Butt (ACL) will also miss Monday's game, but he likely could be moved to injured reserve before kickoff to allow the Broncos to add a healthy player to their active roster.
UPDATE [2:38 p.m. MT]: The Broncos placed Butt on IR and promoted Brian Parker from the practice squad.
