Wide receiver Marlon Brown suffered a concussion early in the second quarter of Sunday's Ravens-Chargers game and was ruled out for the remainder.
He went high to catch a floating pass from quarterback Joe Flacco. He caught it for an 8-yard gain and first down, but Brown came down hard on the turf.
Trainers and teammates huddled around him for a few minutes before he went to the locker room to be evaluated for a concussion. He was shortly thereafter ruled out.
Brown was having his best game of the season before the injury.
He had three catches for 25 yards on the day, including a one-handed 7-yard catch on a third-down throw a little high and behind him that kept the Ravens' first touchdown drive alive.
Brown hasn't been nearly as big a part of the Ravens offense this season after tying a franchise rookie record with seven touchdown catches last year. He had shown up more in recent weeks, however. He had six catches for 59 yards in the previous three games.
Ravens cornerback Anthony Levine also went down on the final kickoff of the first half, but returned to the field on the Chargers' first drive of the second half.
