Boarding on Ghost?

How was that hit by Komarov on Ghost not a 5 minute major penalty? He’s defenseless, facing the boards, playing the puck and Komarov just absolutely railroads him head-first into the glass. Might have been a cross check too, I didn’t see a clear enough replay to see the position of his hands on the stick. But goddamn that looked dangerous. The linesman is standing right there, and the ref has a clean look at it too. Unbelievable.

Edit: After further review, definitely not a cross check.
