DENVER -- Denver Broncos quarterback Teddy Bridgewater departed Sunday's 23-7 loss to the Baltimore Ravens with a concussion.
Bridgewater --- who took several big hits in the opening half, including on his last pass attempt before halftime -- was evaluated for a concussion at the half before officially being ruled out in the third quarter.
Drew Lock took over at quarterback to start the second half with the Broncos trailing 17-7. He finished the game 12-of-21 passing for 113 yards with an interception.
The Broncos, who started two backup guards -- Netane Muti and Quinn Meinerz -- in the game, had struggled to protect Bridgewater in the first half.
