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.— NHL Player Safety (@NHLPlayerSafety) March 9, 2016
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.— Amalie Benjamin (@AmalieBenjamin) March 9, 2016
The hit, for those who missed it:
John-Michael Liles to have hearing w/ NHL about this hit. Clean history & no injury, but should at least be fined. pic.twitter.com/08U63Q8cjq— Pete Blackburn (@PeteBlackburn) March 9, 2016
Usually, not mentioning "in-person hearing" means it will be a phone hearing, so it clearly won't be major discipline coming.
Fine? One game on the sidelines?
