Straight from the source:
Boston's John-Michael Liles will have a hearing tomorrow for an illegal check to the head on Tampa Bay's Nikita Kucherov.

The Globe's Amalie Benjamin notes that Liles' past is unlikely to factor in here:
John-Michael Liles has one fine, for kneeing in 2006, on discipline record. Unlikely to be any significant factor in upcoming hearing.
