Reports at the weekend suggested Gregory was disillusioned with the game and considering bowing out, but he said yesterday that he intended to continue to coach a club at which he has enjoyed considerable success since his appointment nearly three years ago.
"I'd like to spend the rest of my career at Salford," he said. "I don't know where these stories come from. I'd be stupid to consider quitting after finishing sixth in Super League last season."
The London Broncos are unlikely to succeed in a bid to have their new recruit, Luke Goodwin, registered retrospectively for the Challenge Cup.
The former Oldham player, who has also appeared for a string of clubs in his native Australia, is expected to complete his signing today, replacing Deon Bird, who has failed to get a work permit, in the London squad.
London's argument is that, since Bird's absence is none of their fault, his Cup registration should be transferred to Goodwin, but that is unlikely to impress the League.
St Helens are in a similar situation, having signed Damien Smith to replace Jamie Olejnik, and will get a similar answer if they try to incorporate him in their Cup campaign.
Graeme Bradley, the Bulls captain, could face disciplinary action from the League over a newspaper column in which he criticised the referee Steve Nicholson over his handling of Bradford's Cup tie at Rochdale.
