The Denver Broncos returned returned to the practice field on Wednesday, veteran safety Brian Dawkins (neck) was again absent. Fullback Spencer Larsen (knee sprain) was also held out of practice.
Dawkins has missed the team's last three games, all of which Denver lost. Larsen was injured last week against Kansas City.
Broncos rookie fullback Austin Sylvester is expected to make his NFL debut on Sunday if Larsen is not able to play. Recently signed offensive lineman Ryan Harris could also make his 2011 debut with the Broncos on Sunday, providing depth to the Broncos offensive line.
Harris and linebacker Brian Iwuh, whom the Broncos signed on Tuesday, have been assigned jersey numbers 72 and 59, respectively. Iwuh most recently played with the Chicago Bears as a special teams player.
Kickoff on Sunday at Sports Authority Field is scheduled for 2:30 p.m. (MT). The game will be broadcast on CBS.
