ENGLEWOOD, Colo. — Cornerback Bryce Callahan was listed as questionable for Monday's game against the Raiders on the Broncos' final injury report of the week.
Callahan was listed as limited for each practice this week.
Linebacker Todd Davis (calf) is listed as doubtful, while fullback Andy Janovich (pectoral) and linebacker Joe Jones (triceps) were ruled out. All three players did not practice this week.
Safety Trey Marshall, who was limited earlier in the week, was a full participant on Saturday and is "ready to go," according to Head Coach Vic Fangio.
"50-50," said Fangio when asked the odds of Callahan playing. "That's what questionable means."
If Callahan cannot play, Fangio said the Broncos will substitute different players depending on the defensive package.
Fangio said the Broncos will "probably" decide on Sunday whether Davis plays against Oakland. If he is out, Fangio said it will be "a mix" of Alexander Johnson, Corey Nelson and other reserves who will play linebacker.
"[Nelson has] done extremely well mentally, which was a tall task for him," Fangio said. "Obviously him already being in somebody else's camp helped, so he's not having to get in football shape. He's already there. He's done a great job picking up the system."
The Broncos will release their list of seven inactive active players 90 minutes before kickoff on Monday.
