Harrison, who threatened to retire after the NFL’s crackdown, was fined for his tackle of Browns receiver Mohamed Massaquoi(notes), who suffered a concussion. He also had a hard hit on former college teammate Joshua Cribbs(notes).

On Friday, Cribbs told his friend not to change the way he plays, and that Harrison’s job is to simply “knock people out.”

Cribbs, who played at Kent State with Harrison, believes he helped persuade Pittsburgh’s big hitter not to retire.

I'm glad at least one Brown is an old school tough guy that likes to play football.
