Some other brawls that come to mind.
An earlier Bradford one (not the 2000 all in brawl), probably around 1996 or 97, if I remember rightly the brawl happened on the opposite side of the pitch to Richard Henare so he just got hold of the nearest Bradford player (Glen Tomlinson?) and started punching him.
First game of the season against Wigan in 2001, Toa had been sent off and there was some needle going on, Nutley and Nikau were looking to start on people and there were fights every few minutes. I think Kidwell got sin binned, Nikau ended up getting sent off. The one I remember here was Dave Highton who had just come out of the Academy but was getting stuck right in to David Furner who was a pretty hard nut from Australia.
