FOXBOROUGH, Mass. -- Buffalo Bills quarterback Ryan Fitzpatrick called New England Patriots linebacker Brandon Spikes a “punk” after the Patriots’ 37-31 win, during which Spikes was called for an unnecessary roughness penalty on a third-quarter shot to Fitzpatrick’s head that left him on the ground without a helmet.

"I think the biggest thing is we're not going to back down from anybody," Fitzpatrick said after Sunday’s Bills loss. "I think that Spikes is an emotional player. I think that he's a punk, at times. (He) took a cheap shot at Scott (Chandler) in the first game (the teams played this season). He was doing a lot of jabbering and talking and hitting out there. (He's) not one of my favorite players, not high on my list."

The hit on Bills tight end Chandler that Fitzpatrick referred to resulted in Spikes receiving a $21,000 fine from the NFL and forced Chandler out of the game with a concussion.
