Steelers coach Mike Tomlin says the hit linebacker James Harrison made on Browns wide receiver Mohamed Massaquoi was within the rules. The NFL is reviewing whether Harrison's concussion-causing hit on Massaquoi warrants a fine or suspension. "I'm all for player safety. I think it is the proper initiative that the NFL has," Tomlin said. "I think we need to safeguard the men that play this game to the best of our abilities and make it as safe as we can. I'm a proponent of player safety and whatever rule or rule adjustments we need to make to make it safer."
