Broncos wide receiver Demaryius Thomas left after the first series of Denver's game against the Kansas City Chiefs on Sunday with a shoulder injury. His return was questionable.
The Broncos were already missing several starters due to injuries.
Defensive tackle Kevin Vickerson went on injured reserve this week after dislocating his right hip, defensive end Derek Wolfe was left behind in Denver after he was hospitalized Friday with some seizure-like symptoms, cornerback Antonio Rodgers-Cromartie was out with a shoulder injury and tight end Julius Thomas was inactive with a lingering knee injury.
Demaryius Thomas came into the game needing 45 yards receiving for back-to-back 1,000-yard seasons. He had one catch for 14 yards on the Broncos' first possession.
