ENGLEWOOD, Colo. — Outside linebacker Von Miller is officially questionable for Sunday's game against the Texans.

Miller was limited in Friday's practice, as he was during both practices earlier in the week.

Head Coach Vic Fangio said Miller may test his knee on the field before Sunday's game, like he did before the Broncos' Week 13 game against the Chargers.

Miller did not play against Los Angeles, which snapped a 95-game active streak for the outside linebacker.

Fangio, though, said Miller has improved since last weekend.

"He's much better than he was last week," Fangio said.

Outside linebacker Malik Reed (ankle/shoulder) and tackle Ja'Wuan James (knee) are also questionable. Guard Ron Leary (concussion) has been ruled out, and Austin Schlottmann will start in his place.

Reed was limited on Thursday and Friday after missing Wednesday's practice. James was full in practice all week, but he is not 100 percent certain to play against the Texans.

"I just don't want to put him out there if he's not going to play good," Fangio said, "so we'll see how he shows up tomorrow and Sunday."

Fangio said there's "a good chance" James would start if he plays, but he would not take every offensive snap.

The rest of the Broncos on the team's injury report were full participants on Friday, with the exception of wide receiver Courtland Sutton. He was added to the injury report with a hamstring injury and was limited on Friday.
