PITTSBURGH – The Browns lost two wide receivers and their lead in the second quarter Sunday. Pittsburgh led 7-3 at halftime, but the big news was receivers Joshua Cribbs and Mohamed Massaquoi left the game following hits to the head by linebacker James Harrison. Neither play drew a penalty, although the Browns sidelined was calling for one. Joshua Cribbs was knocked out of the game after being knocked out on his feet on a helmet-to-helmet hit by Harrison. The injury was announced as a head injury (read: concussion) and he a return was ruled out. Cribbs was the Wildcat quarterback and looking to pass but no one was open. When he pulled the ball down and tried to run, Harrison made vicious contact as Cribbs was going down. Cribbs immediately went limp, with the ball falling from his arms. He lay facedown for a couple of minutes as his teammates prayed and Steelers quarterback Ben Roethlisberger stood close to check on his former Mid-American Conference rival. Cribbs was able to walk off the field and walked on his own power to the locker room after arguing with a team doctor to return to the game. Cribbs yelled back at a Steelers fan on his way to the locker room. Harrison and Cribbs are Kent State alum. Massaquoi walked to the locker room later in the half after he dropped a pass over the middle and Harrison hit him in the head with his arms. Massaquoi, who appeared to be defenseless, got up dazed and left the game. No official announcement was made, but he could also have a concussion. Things could get interesting in the second half if the Browns look for retribution. The Steelers went up 7-3 on a 29-yard pass from Roethlisberger to Mike Wallace, who made a nice adjustment with the ball in the air to beat cornerback Eric Wright. It was Roethlisberger’s first touchdown of the season. Browns linebacker Matt Roth was about to hit Roethlisberger when he released.
