It will be interesting to see how Player Safety views this one. There's no question that Domi going down is what caused the head contact. But, did Trouba have enough time to avoid the hit, or was he already committed?
Trouba was not issued a penalty for his hit on Domi, but he did go off for 5 minutes for fighting. The Canes were forced to kill a penalty though, as Lorentz got 5 for fighting, 2 for instigating and a 10 minute misconduct. The Rangers scored on the ensuing power play and never relinquished the lead, taking Game 4 to tie the series up at 2 games apiece.
