ENGLEWOOD, Colo. — Outside linebacker Bradley Chubb and running back Phillip Lindsay did not practice again on Thursday, and their status for Sunday's game against the Chargers may be in jeopardy.

Head Coach Vic Fangio said Thursday he was unsure whether either player would be available in Week 16.

"We'll see how they progress through the week," Fangio said. "Hopefully we might be able to get them to practice on Saturday some before we take off for LA. We'll see. I do think it's going to go down to the wire."

The Broncos are not scheduled to practice Friday because of the Christmas holiday.

"Ever since we've lost our bye week — I think we're the only team in the league that didn't get a bye week — I've tried to give them a day or two whenever I can," Fangio said. "We've added a few practice reps to yesterday's practice [and] today's practice, and we'll do a little bit more on Saturday than we normally do to compensate for not practicing on Christmas Day. I think it's always nice if you can, if the schedule works out, that you do give the players Christmas off to spend time with their family."

Chubb suffered an ankle injury on Saturday against the Bills, while Lindsay is dealing with injuries to his hip and knee.

Chubb continued to work on the side with trainers during the media-viewing portion of Thursday's practice. Royce Freeman participated on a limited basis.

Lindsay was absent from practice again on Thursday.

Cornerback Nate Hairston was added to the injury report with a toe injury and did not practice.

Defensive lineman DeShawn Williams (knee) and tackle Demar Dotson (hand/not injury related) were limited participants, while guard Graham Glasgow (foot/hand) and defensive end Shelby Harris (elbow) were full participants.
