Pittsburgh Steelers receiver Diontae Johnson suffered a devastating head injury on an illegal hit during Thursday's game against the Cleveland Browns.  

He was seen on the sideline bleeding from the ear while walking to the locker room:

Johnson was attempting to catch an overthrown pass in the third quarter when Brown safety Damarious Randall laid a helmet-to-helmet hit on the defenseless receiver. Randall was flagged for unnecessary roughness and ejected.

The receiver was later declared out with a concussion.

He was the second Steelers receiver to suffer a concussion in the game, after JuJu Smith-Schuster also went out after a questionable hit from the Browns defense.
