Lock (shoulder) was a full participant in Wednesday's practice, James Palmer of NFL Network reports.
Lock missed Denver's last two games due to a strained shoulder, but his ability to practice in full to begin Week 6 puts him in position to reclaim starting duties Sunday against the Patriots. According to Nick Kosmider of The Athletic, head coach Vic Fangio has yet to announce that Lock will be fit to start this weekend, but that should merely be a formality if he's able to continue practicing fully Thursday and Friday.
