There was no doubt at all about his guilt.
Shelford, who would take over as All Blacks captain the following year, had struck out in retaliation for the Welshman first lashing out at teammate Gary Whetton. Nowadays the incident probably would have seen about four red cards, 34 TMO replays, a hefty few post match bans and a moral crusade to 'ban this sick filth' from our televisions.
Except, well, this was 1987 and things were a bit different then. Watch the video and see for yourself.
The result was a red card for Richards and a penalty to the All Blacks!
The Welshman was subsequently given a one week ban and forced to miss the third place playoff against Australia (unlike today, no concussion test would have prevented him playing if he hadn't been banned).
Shelford, meanwhile, played in the final against France and was key in a 29-6 win over France.
24 years is a long time in sport.
