Steelers outside linebacker Bud Dupree was indeed fined for his nasty hit on Dolphins quarterback Matt Moore last week, ESPN.com reported.
According to Dupree, he hasn't seen the dollar amount yet, but he plans to appeal the fine.

ESPN also reported that the fine is $18,231, standard for a first-time roughing the quarterback call.
Moore was hit by the crown of Dupree's helmet in the chin area, causing his head to snap to the side. He left the field after a few minutes but missed only one play as a result of the hit.
Moore returned to the game, but the Dolphins eventually lost, eliminating Miami and sending Pittsburgh to the AFC divisional round.
Moore said after the game he felt like he didn't sustain a concussion, but the NFL and NFLPA are investigating whether the league's concussion protocol was followed.
