I remember back when I was a kid at the hockey rink where these middle aged people were talking about old time hockey, and this guy asked "didn't Mikita get into a fight in an all star game?" I couldn't find any reference to it, so perhaps not...but that got me wondering, did that guy confuse Mikita with someone else that fought?
At Chicago Stadium in 1948 Gordie Howe and Gus Mortson surprised fans by dropping the gloves "with full vim and vigour." Apparently the two hockey stars went at it so hard that it was decided they would not serve the 5 minute sentence in the penalty box. You see, back then the penalty box was basically shared by each team, with little to stop angry players to continue their disagreement. It was decided Howe and Mortson would stay on their own team's bench, but under police guard!
NHL "stars" played two more exhibition games in the 1930s to benefit families of Montreal players Howie Morenz and Babe Siebert, who both died prematurely, but the true foundation of the modern-day event took place in 1947 when the Stanley Cup champions from the previous season played the best of the rest in a preseason contest.
That format lasted four years, and it was taken seriously enough by players that the legendary Gordie Howe even got into a couple of fights.
"There was a lot more intensity then," Howe once said, recalling the fights he had in 1948 with Gus Mortson and in 1951 with Maurice Richard. "You hated those ********."
