THE DENVER Broncos might have to face former quarterback Kyle Orton with two backup safeties if Brian Dawkins and Quinton Carter can't play in Sunday's showdown with the visiting Kansas City Chiefs, who are trying to deny Tim Tebow a trip to the playoffs.

Although Carter (hip) participated in the entire 2-hour workout yesterday, Dawkins was held out of the team's final full-padded practice of the regular season because of a neck injury that has bothered him for much of the month. Dawkins didn't address his availability for Sunday but did dismiss speculation that the injury threatens his 16-year career.

Dawkins, Carter and nickel cornerback Chris Harris (neck) with 62 tackles, were knocked out of last week's loss at Buffalo.

If Dawkins can't play, David Bruton would start at strong safety even though he was limited at practice because of a nagging Achilles' injury.

In another matter, the league changed one of Tebow's four interceptions against the Bills to a sack and fumble.
