Lock (ribs) didn't practice Wednesday, Aric DiLalla of the Broncos' official site reports.

EDGE Analysis

Coach Vic Fangio noted that Lock's ability to play Sunday against the Dolphins figures to depend on a few factors that will be evaluated as the week rolls along, while adding that the team does want the QB to see some practice reps in advance of the weekend. As long as Lock misses or is limited at practice, however, Brett Rypien will continue to see added first-team work in his place.
