Kick returner Trindon Holliday is doubtful for the Denver Broncos' season finale against Kansas City because of a sprained ankle that has sidelined him all week.
Also, cornerback Tracy Porter (concussion) was ruled out for Sunday while right guard Chris Kuper is 50-50 after participating on a limited basis for the second straight day. He's been sidelined with a sprained left ankle and migraines.
Kuper has played in just six games this season. He missed the first month with a broken forearm and five of the last seven games after spraining his left ankle, the same one in which he tore ligaments in a gruesome injury on New Year's Day.
Coach John Fox said he wasn't worried about Kuper's availability heading into the playoffs.
