PITTSBURGH -- Pittsburgh Steelers linebacker James Harrison states his objective matter-of-factly: He's out to hurt any opposing player who roams into his vicinity.

If he sees players down on the turf -- as he did Sunday when he sidelined Browns wide receivers Josh Cribbs and Mohamed Massaquoi with concussion-causing hits only minutes apart -- he knows he has done his job.

"I don't want to injure anybody," Harrison said following Pittsburgh's 28-10 victory. "There's a big difference between being hurt and being injured. You get hurt, you shake it off and come back the next series or the next game. I try to hurt people."

Harrison's reputation as being one of the NFL's nastiest players was enhanced when his leading-with-the-helmet hits on Cribbs and Massaquoi left the Browns with just two healthy wide receivers for more than a half. Neither hit was penalized, although the NFL said Monday it is reviewing the hit on Massaquoi. The league determined the tackle on Cribbs was legal.

Harrison defended his hits after the game.

"If I get fined for that, it's going to be a travesty," Harrison said. "They didn't call [a penalty] on that. There's no way I could be fined for that. It was a good, clean, legit hit. ... I didn't hit that hard, to be honest with you. When you get a guy on the ground, it's a perfect tackle."

Harrison's style of play is raising questions about whether it's possible to stay within the rules, yet also play dirty. While the Browns weren't especially critical of the hits following the game, tight end Benjamin Watson was more outspoken Monday.

"I hope the NFL does the max, whatever the max is, I hope they give it to him," Watson said.

NFL vice president of football operations Ray Anderson told The Associated Press that the league could soon start suspending players for dangerous helmet-to-helmet hits. The NFL is emphasizing a reduction in football concussions, which can lead to dementia and brain disease.
