ENGLEWOOD, Colo. — As the Broncos continue to evaluate who will start at quarterback for Sunday's matchup with the Chargers, they have made rookie quarterback Drew Lock available after activating him from injured reserve on Saturday.
In a corresponding move, they waived quarterback Brett Rypien, who has served as the Broncos' backup quarterback since the team placed Joe Flacco on injured reserve after Week 8 with a neck injury.
Lock had been on injured reserve since suffering a thumb injury during an Aug. 19 preseason game against the 49ers. As one of two players the Broncos designated for a possible return from injured reserve, Lock began practicing again prior to the Broncos' Week 11 game vs. the Vikings.
In the wake of significant offensive woes in a 20-3 loss to the Bills, the Broncos began ramping up Lock's practice reps on Wednesday. Head Coach Vic Fangio said on Wednesday that Lock would get 75 percent of the offensive snaps.
"Good," Fangio said on Friday when asked about how Lock performed throughout the week of practice. "I think he's made progress each and every day. When you go from getting basically 10 out of 40 or 42 reps to getting 32 out of 42 [reps] three days in a row, you should get a little better and feel a little more comfortable. I think he has."
But Fangio said whether Lock or Brandon Allen will start on Sunday could be decided as late as Saturday. Allen has started the last three games for the Broncos.
"I just want a chance to go ahead and look at the tape more extensively," Fangio said after Friday's practice.
For his part, Lock said Wednesday that the timing of the ultimate decision won't affect him.
"I'm prepping to be a starter," Lock said. "If that happens, then that happens. If it doesn't, then it doesn't. I'll be ready either way, to either help Brandon out this week or hopefully have Brandon help me out."
The Broncos also now have an open spot on their 10-man practice squad, as offensive lineman Corey Levin was signed to the Bears' active roster.
