The only way I see to stop or greatly curtail head shots is that the offending party gets suspended until the injured party returns. Head shots are occurring to often with players being out for an untold number of games while the offending party comes back after a short suspension. These head shots have ended some careers early and in some cases some brain damage has occurred. Cheap shots in the NHL should be dealt with severely. Also in the case of any cheap shot should be called not only by the referees but by the linesmen also 4 pairs of eyes are better than two.
