After what we saw not too long ago with Adam Johnson in the U.K., it does prompt the question of whether or not neck guards should be compulsory to avoid the risk of neck cuts altogether. Of course, it's not all too common, it's never done maliciously, and it's hard to predict if it will ever happen again, but as we saw in England, it can be a life or death situation.
Some players have opted into wearing neck guards and the Pittsburgh Penguins were the first club to mandate the use of the equipment on their AHL and ECHL affiliates, but many believe that it will take awhile for the NHL to follow the trend.
Fortunately for Scheifele, he not only escaped the situation without any scratches, he was also not given a penalty for the obvious trip either.
