Wes Welker and Champ Bailey both sustained injuries during the Denver Broncos' 40-10 defeat to the Seattle Seahawks last night.
Welker, who scored the Broncos' only touchdown during the game, suffered a right ankle sprain, but the team have not indicated how serious the injury is.
Bailey left the game on crutches after injuring his foot, although X-rays have already ruled out a fracture.
The cornerback will undergo an MRI scan to determine the full extent of the damage.
Meanwhile, defensive end Derek Wolfe has been cleared to fly back to Denver with the team after tests for a cervical spine injury came back negative.
