Boston Bruins forward Shawn Thornton's appeal hearing for his 15-game suspension will be held with the National Hockey League on Friday.

Thornton's agent, Anton Thun, confirmed on Monday that his client was appealing the punishment, which was given to Thornton for punching and injuring unsuspecting Penguins defenceman Brooks Orpik two Saturdays ago. The NHL Players' Association announced it had informed the league of that plan before the 48-hour deadline to do so passed.

The appeal hearing will be conducted with NHL commissioner Gary Bettman. If Bettman upholds the suspension, Thornton and the NHLPA can then elect to appeal to a neutral arbitrator because it is for six or more games.
