The Denver Broncos linebacker, who had 18.5 sacks in 2012, is eligible to return against the Indianapolis Colts this weekend.
The head coach told reporters: "He's a special player. He's very, very talented, one of the better pass rushers, in my opinion, in the league.
"We'll see how it goes in practice. I haven't watched him practice in six weeks. He's been in the building, he's been at meetings, he's been with our strength and conditioning coaches, so he looks great. We'll see how he looks in practice tomorrow."
The Broncos sit at the top of the AFC West, having won all of their games so far this year.
