Nathan MacKinnon is down on the ice here in Ottawa. He tried to reverse hit Artem Zub and immediate went down and grabbed his side.
Cale Makar also just went to the room ahead of that 4v3.
For those interested in MacKinnon's story:
Pavel Francouz said that during his first or second season with the Avalanche, he once ordered fried cheese with fries for dinner. When the waiter brought it to the table, MacKinnon immediately had a problem with it and basically asked him how he could possibly order something like that, adding that it would be the last time he'd ever see him eating something like that.
Another player (I believe it was Rantanen) had to step in to calm things down a bit.
Anyway, Francouz never ordered anything like that at a team dinner again. He understood that MacKinnon is simply a winner who wants to win at all costs. They went on to win the Stanley Cup later.
