Three Denver Broncos were listed as non-participants at practice on Wednesday, including starting right guard Chris Kuper.
Kuper has been on the team's injury report for weeks with a recurring ankle issue, but the seventh-year veteran out of North Dakota now has an accompanying head injury heading into Denver's Week 17 meeting with the Kansas City Chiefs. Wide receiver Trindon Holliday, who has an ankle injury of his own, sat out on Wednesday, as did cornerback Tracy Porter, who is listed on the report with a concussion.
Wide receiver Matthew Willis (knee), fullback Chris Gronkowski (hamstring) and safeties Mike Adams (knee) and Jim Leonhard (thigh) are also on the injury report, but were listed as full participants in practice.
The Broncos (12-3) and Chiefs (2-13) will kick off at 2:25 p.m. MT on Sunday from Sports Authority Field at Mile High in Denver, Colo. The game will be televised on CBS.
