Gower? Australian prop - can't even remember his name?

I assume you are thinking of Mark Carroll.

Not Carroll, Kafusi or something like that, went to Huddersfield I think

Mark Carroll, a player who came over to bash up a few mommies. Turned out to be a waste of space.

That was pommies!!!

I recall a tear up he had with a St Helens prop (Can't recall his name), which led to an all out brawl, that included Shaun Edwards vs Sean Long.
Also resulted in claret streaming down Carroll's face!

Kafusi turned out considerably better than Carroll.

Craig Gower the ex Aussie Half back maybe

Havent Marquee players only been introduced in the last couple of years
