Hoyer stayed on the turf for several minutes but eventually walked off the field under his own power. The quarterback appeared to be clutching his left arm when examined by members of the Bears' medical staff.
Bears guard Kyle Long also left the game in the second quarter with an arm injury and did not return. He was near Hoyer when the quarterback suffered the injury.
"I just saw that Brian stepped up on the play, and then I turned around and he was down," Long said. "I tried to help him up, but I knew right away there was something wrong."
Hoyer was 4-of-11 for 49 yards before he left the field. He was replaced byMatt Barkley, who finished 6-of-15 for 81 yards with no touchdowns and two interceptions. Veteran Jay Cutlerwas inactive because of a thumb injury.
"It is not a good feeling seeing a teammate go down like that," Bears tight end Zach Miller said. "But it is the nature of the game, and he took a shot. You have to dial it back a little bit when Matt Barkley came in, but we tried to stick to the game plan. We adjusted a few things, but we weren't going to change much, maybe a couple different checks at the line. It was just a weird night."
Long said his arm was also seriously injured.
"I was ready to go back in if it was an emergency situation," Long said. "But they were just trying to be careful. But my arm is f---ed up. So, tough spot to be in."
