ENGLEWOOD, Colo. — As the Broncos turn their focus to a Week 17 matchup with the Chargers, starting quarterback Teddy Bridgewater remains in the concussion protocol, Head Coach Vic Fangio said Monday.

Bridgewater missed Sunday's loss to the Raiders as he recovers from a concussion that he suffered during Denver's Week 15 loss to Cincinnati.

"There is no update on Teddy," Fangio said. "He's still in the all the concussion protocols and working with the independent docs on that. We really don't have an update as far as whether he'd be available or not this week. Maybe as the week moves on we will, but until he's cleared by the independent docs and says he's ready to go, we have to assume he won't be available to play. We'll do the best thing for him, moving forward."

In Bridgewater's absence, third-year quarterback Drew Lock made his first start of the season. He completed 15-of-22 passes for 153 yards, zero touchdowns, zero interceptions and a passer rating of 87.9.

Fangio also told press on Monday that the team will be without defensive lineman DeShawn Williams for the final two games of the season after suffering an elbow injury during Sunday's game. Williams had appeared in all 15 of Denver's games, including eight starts, and he recorded 39 total tackles, one sack, two passes defensed, five quarterback hits and one tackle for loss.

Defensive lineman Mike Purcell's status may also be in question, as Fangio said he may be entering COVID-19 protocols, depending on forthcoming test results.
