Fighting for a puck in front of the net, Mason Marchment took his stick right up Josh Manson's face. Therefore setting a call for a 2-minute high-sticking and possibly a 4-minute penalty if Manson had been bleeding.
The call the referee made on the ice, was that since the play was stopped because Manson failed to get back up, the determining element of the call was whether or not there had been an injury.
