VIDEO: Bruins' Liles not penalized after hit to Kucherov's head

Boston Bruins defenseman John-Michael Liles somehow escaped a trip to the penalty box for a hit during Tuesday's game against the Tampa Bay Lightning, but it won't be a shock if he hears from the NHL's Department of Player Safety.

During the first period, Liles delivered a dangerous forearm to the head of Lightning forward Nikita Kucherov, who struggled to get back to his feet.

Kucherov, Tampa's leading scorer, went straight to the dressing room, but returned for the start of the second.
