Wake delivered a blow to Panthers quarterback Cam Newton’s chin on the first play of the day, leaving Newton spitting up blood while the game went on without any penalty to Wake. The league disagreed with referee Scott Green’s crew belief that Wake’s hit fell within the rules and has confirmed with PFT that the Dolphin pass rusher has been fined $15,750 for roughing the passer.
