Harris, who suffered a left shoulder injury in the Broncos' regular-season finale against the San Diego Chargers, practiced fully through the week, and Kubiak said the two-time Pro Bowl selection has shown he's ready to face the New England Patriots' high-powered passing attack.
"I think Chris is fine," Kubiak said after Friday's practice. "He had a good week. ... Everything I've seen this week in practice tells me Chris is fine, ready to go. ... I think he's feeling a lot better than going into last week's game."
Harris played in obvious pain against the Pittsburgh Steelers in Sunday's AFC divisional round win. As a result, Harris came off the field against the Steelers far more than he usually does in games, playing in 47 of the team's defensive 63 snaps.
Harris was the only player on the Broncos defense who topped 1,000 snaps in the regular season.
"Just watching him work, doing the things he does when he's covering well and being physical," Kubiak said. "He's been able to do that all week; we've had a really good week of work."
Harris said this week he felt "light-years ahead" of how he felt last week leading up to the AFC's divisional round game.
The Broncos did dial back cornerback Bradley Roby at least some in practice Friday because of a sore hip, but Kubiak said that was just a precaution and that Roby will be ready to play against the Patriots.
