Baltimore Ravens cornerback Asa Jackson left Thursday night's game against the Pittsburgh Steelers with a concussion.

Jackson started the game for the Ravens in place of Chykie Brown, who ended up replacing him in the lineup after his injury forced him out of the game in the second quarter. Any extended absence from Jackson would leave the Ravens with precious little depth in their defensive backfield behind Brown and fellow cornerback Jimmy Smith. Cornerback Lardarius Webb has been sidelined with a back injury since the second day of training camp. 

The Steelers also had a concussion scare during the game, when wide receiver Antonio Brown had to leave the contest to be evaluated for a potential concussion. Brown was eventually cleared under the NFL's concussion protocol and returned to the game.
