The Ravens suffered injuries to two offensive starters in the first half of Thursday night's game.
Wide receiver Jacoby Jones suffered a sprained right knee and right tackle Michael Oher sprained his ankle. Both left the game and did not return.
Head Coach John Harbaugh did not have any update on their status after the game.
"Whenever you lose two starters, it's going to hurt you in some way," quarterback Joe Flacco said.
Midway through the second quarter, rookie free agent safety Brynden Trawick collided with Jones on a punt return. Trawick never looked up to see Jones, who was calling for a fair catch. Jones didn't see his teammate coming.
The two remained on the ground for a little bit before both headed to the bench. Jones was quickly evaluated by team doctors and taken to the locker room.
Rookie free agent wide receiver Marlon Brown entered the game for Jones, who had three catches for 24 yards through a little more than a quarter of play. Brown finished with four catches for 65 yards and a touchdown.
Right tackle Michael Oher also suffered an injury in the second quarter. He turned his ankle when Marshal Yanda fell into him during Ray Rice's 1-yard touchdown run.
Oher limped off the field and did not return. He was replaced by rookie fifth-round pick Rick Wagner.
"I'm good. We have to wait on the test results but everything should be OK," Oher said after the game.
Jones and Oher will continue to be evaluated this week. The Ravens have a longer rest than usual after their Thursday night game. They don't play again until the Browns come to Baltimore on Sept. 15, giving Jones and Oher more time to recuperate.
