Running back LenDale White was down for a while during the second quarter and gingerly walked off the field after being hurt on a 9-yard run. The Broncos said White's return was doubtful.
The Broncosalso tweeted that offensive tackle Ryan Harris suffered a left ankle injury and wasn't expected to return. The team already was keeping a close eye on All-Pro tackle Ryan Clady, who returned to the field Wednesday for the first time since he blew out his left knee during a pickup basketball game in April.
