Johnny Manziel now in concussion protocol as symptoms linger

Montreal Alouettes quarterback Johnny Manziel was placed under the CFL concussion protocol on Wednesday.

He was rocked by a hit while trying to run the ball over the goal-line in a 24-17 loss in Ottawa last weekend in his second career CFL start.

"On Tuesday morning, Johnny Manziel mentioned to our medical staff that he felt symptoms that could be associated with the prescribed medication he uses for a previously diagnosed medical condition," the Alouettes said in a statement. "He then missed practice in order to have some blood work done.

Ottawa's pivot threw for 487 yards and completed 44/54 passes to help lead his team to a 24-17 come-from-behind victory at home on Saturday.

"In view of the hit he received on Saturday and the potential mitigating side effects of his prescribed medication, the Alouettes medical staff has placed Manziel under the CFL concussion protocol for further observation and precautionary reasons. Manziel will be closely observed and assessed in the next few days."

The 2012 Heisman Trophy winner struggled in his CFL debut but looked better against the Redblacks. He did fumble after taking the hit but Montreal recovered for the touchdown.

The Alouettes are in Edmonton to face the Eskimos on Saturday night.
