Lamar Jackson has been playing at a MVP level through the first two games of the season. Any injury to Jackson -- who's in a contract year -- would be devastating to him and the Baltimore Ravens. 

That injury scare happened Wednesday, as Jackson was seen during the media portion of practice with a sleeve around his right elbow. Jackson wasn't throwing during the session, either, raising concerns about what's wrong with his arm that the Ravens haven't revealed yet. 

Head coach John Harbaugh quickly eased those concerns after practice. 

"It's just a normal course of the season type thing," Harbaugh said Wednesday. "He practiced today. He'll be playing on Sunday."
