That is par for the course for that scumbag, and Lee Evans agrees:
"Although no such records are kept by the league, he is believed to hold the record for most times fined by the league for unnecessary roughness or unsportsmanlike conduct. Notorious for his cheap shots, Harrison was voted the dirtiest player in the NFL by his peers according to a poll conducted by Sports Illustrated. In 2006, Harrison further solidified his reputation as one of the dirtiest players in NFL history when he, yet again, topped the list of the dirtiest players compiled by Sports Illustrated. Of the 361 NFL players polled during the preseason, an incredible 23 percent of them pointed to Harrison as the league's dirtiest player. When interviewed about Harrison for an October 19, 2006 Boston Herald article, Buffalo receiver Lee Evans supported the notion that Harrison is a dirty player, “you can see it on film. It will be subtle, like making a tackle and doing something a little extra after it. You’re getting up and maybe he pushes your face into the ground or gives you a little kick in the back."
