Thornton went after Orpik during a stoppage in play Dec. 7, slew-footing him to the ice and punching him twice. Orpik sustained a concussion and was taken off the ice on a stretcher. Earlier, Orpik hit Boston's Loui Eriksson, knocking him out of the game with a concussion.
Thornton was assessed a match penalty.
Orpik hasn't played since the game.
The suspension will cost Thornton $84,615. He served three games of the ban before the length of the suspension was determined.
You can be hyped all you want, but his game will speak for itself. He's obviously going to be a great player so we've got to make sure we keep an eye on him. Whether it's his first game or his 1,000th game, our job is to take care of business, shut him down.
