The Bulldogs and Cronulla have bared their jaws ahead of Sunday's grudge match, with club bosses exchanging verbal slurs over player discipline.

Coach Brad Fittler says he's resigned to being without Bulldogs backrower Nick Kouparitsas as a late inclusion in his Sydney Roosters team for Friday's NRL clash with Parramatta after a club switch was delayed.

Parramatta half-back Brett Finch claims that booze bans on NRL players are taking the fun out of a game which is fast losing its characters.

Brent Tate conceded giving up league was a real option as he prepared for a second knee reconstruction in two years.

The dramas at the Sydney Roosters and Bulldogs intersected in bizarre circumstances when the clubs were involved in a mix-up over the future of forward Nick Kouparitsas.

Had Aaron Gorrell not defied St George-Illawarra, there's every chance he could have ended up pouring Dragons fans beers rather than copping their jeers on Friday night.

The bruising defence of Brisbane's hustling half-back Peter Wallace is certain to earn him a fresh crack at the New South Wales Origin No.7 jumper.

His pace and ball skills have made him a stand-out of the Toyota Cup with a premiership and rave reviews that have placed him firmly on the radar of rival clubs.

Parramatta captain Nathan Cayless has called for the NRL to establish a set of guidelines on player behaviour, claiming current rulings on the hot topic were "all over the shop''.
