Pedantic maybe, but it would have been hypothermia. Hyperthermia most unusual in St Helens.

I seem to recall a full back by the name of George Bryan who played druing the London Crusaders days and once suffered frostbite during a game at Crystal Palace.

Yes, it was a game in the snow against Hull in the Challenge CUp IIRC.

10th. February 1985 (when we were Fulham, and would be for a while longer) against Halifax in the first round of the CC. What really hacked him off was ringing home in Brisbane later and finding out that it had been sunny and pushing 100 there that day! We lost 4-17 and I didn't get to the game as I was snowed in in West London

Agreed
Global warming
