Yep, but it would be a different experience these days
(THESE DAYS...)
Raphael Meade sent off for us - handbags with Martin Kuhl (I think). It was a league game rather than FA Cup
EDIT: Must be this one - 29th April '92 was a Wednesday https://www.11v11.com/matches/brighton-and-hove-albion-v-portsmouth-29-april-1992-125306/
'92 for me. An evening game that we won 2-1, with a couple of red cards for punches thrown and a (minor) pitch invasion.
Hilarious fun as a 13yo lad, pegging it onto the pitch, only to run away when a handful of Pompey came at us :lolol:
