NFL Network Insider Ian Rapoport reported Bridgewater is progressing through the concussion protocol and feeling better but is not expected to partake in today's session, per a source informed of the situation.
Broncos coach Vic Fangio later confirmed that Bridgewater will not practice, but he indicated that it's possible Bridgewater is limited Thursday.
Bridgewater was knocked out of the Broncos' Week 4 loss after taking a helmet-to-helmet shot. Lock took over at halftime, completing 12-of-21 passes for 113 yards and one late interception. Denver didn't score on any of his five possessions.
Fangio expressed confidence in Lock if Bridgewater is unable to play Week 5.
"He views himself -- and I view him -- as a starting quarterback in the NFL," Fangio said.
Bridgewater's status will be updated as he moves through protocol during the week.
