PITTSBURGH -- Steelers linebacker James Harrison was fined $25,000 on Tuesday for his penalized hit on Bills quarterback Ryan Fitzpatrick.

Harrison has four fines this season totaling $125,000.

Harrison drew a roughing-the-passer penalty for hitting Fitzpatrick helmet-first during Pittsburgh's 19-16 overtime victory Sunday.

"James Harrison was fined $25,000 for roughing the passer, specifically he made helmet contact to the chest of the Buffalo quarterback, who was in a defenseless position at the time the contact was made," the NFL said in an e-mail Tuesday to The Associated Press.

After the game, the three-time Pro Bowl linebacker said the play didn't warrant a fine. He compared it to his Nov. 21 roughing-the-passer penalty against Raiders quarterback Jason Campbell that did not draw a fine.

"I'm not expecting a fine," Harrison said. "It's the exact thing as last week. It was the same exact hit. I hit him [Fitzpatrick] the same way I did the quarterback from Oakland and I got the same flag but I didn't get a fine. ... I'm expecting the same thing on this."

Harrison previously was fined $75,000 for a helmet hit on Browns wide receiver Mohamed Massaquoi, $20,000 for a helmet-to-the-back hit on Saints quarterback Drew Brees and $5,000 for a hit on Titans quarterback Vince Young.

On Monday, the league rejected Harrison's appeals of the $75,000 and $20,000 fines, although the Steelers supported Harrison's appeal.
