The play occurred as Lewis and Myers were jockeying for position in a puck battle along the boards when Lewis went to throw a bit of a stiff-arm on Myers, connecting with his face, rather than his upper-body. Myers, clearly frustrated, absolutely levelled Lewis into the end boards, clipping him high.
The decision from the DoPS is a confusing one, given the retaliatory nature of the hit by Myers. It just seems like a reckless, avoidable play. This one is a bit of a head-scratcher.
