It was in the season opener against the Ravens in 2013 when the Pittsburgh Steelers suffered a sudden and shocking blow early in the game, with All-Pro center Maurkice Pouncey suffering a friendly fire injury that resulted in him tearing his ACL. Not only did it knock him out of the game, it knocked him out for the season.
Yesterday, the Steelers lost Pouncey against the Ravens within the first couple of plays after he suffered a finger injury, reportedly the thumb on his right hand, the hand he uses to snap the ball.
