Here's a Chiefs-Broncos injury update ahead of Sunday's game in Denver:
Denver linebacker D.J. Williams took a step backward and cornerback Champ Bailey didn't make any progress Thursday. Williams was limited in his participation Thursday after he practiced fully the day before. Williams has missed four games with a knee injury.
Bailey continued to be limited. It is unlikely Denver will play Bailey unless he practices fully. With the Broncos on the verge of qualifying for the playoffs, so they likely won't push Williams or Bailey.
Meanwhile, defensive end Ebenezer Ekuban practiced on a limited basis after he didn't practice Wednesday with a back issue. Safety Marlon McCree, who has missed several games, practiced on a limited basis Thursday. He has an ankle injury.
In Kansas City, the only significant change was that receiver Mark Bradley didn't practice with a calf injury. He wasn't on the injury list Wednesday. Bradley has been one of the Chiefs' best offensive players at times this season.
