Alex Mack, Cleveland Browns Center, Says James Harrison Played Dirty

Cleveland Browns center Alex Mac, said on Thursday that Pittsburgh Steelers linebacker James Harrison played dirty in Sunday's game.

The NFL fined Harrison $75,000 for a pair of helmet-to-helmet hits on Cleveland's Joshua Cribbs and Mohamed Massaquoi. Both suffered concussions and have not practiced this week.

Mack said Harrison's hit on Cribbs was "a little more innocent" and that he went after running back Peyton Hillis while he was on the ground.

"You're still leading with your head. It's a dumb move no matter what you do. If you watch the game film, (Harrison) was doing that to everyone on every play," Mack reportedly said. "People would be on the ground and he would try to spear them. There's a play on film where Peyton Hillis is tackled and he comes up and spears him. It's like you're being cheap, you're being dirty."

Mack went on to say that the league should do what they can to protect the players.

The NFL announced this week that they will start suspending players for dangerous and flagrant hits.
