Rival boxing promoters Sports Network and Sycuan are embroiled in a dispute over the late postponement of Edinburgh super-featherweight Alex Arthur's world title fight with Joan Guzman.

The bout, which was due to have been held last Saturday evening at Meadowbank, was called-off when Guzman encountered visa problems. But Sycuan, who promote Guzman, insist the fight could have gone ahead, had Sports Network been more helpful.

Sean Gibbons, the Sycuan matchmaker, claimed: "I told Frank Warren of Sports Network on Friday April 18 we were having problems but they did nothing to help. They could have done more.

"We employed the services of an immigration attorney but he messed up, not realising that Guzman is Dominican. We started emailing the British Consulate on Tuesday April 22 but Sports Network panicked and cancelled the fight."

But Warren, who is said to be looking at switching the fight to London on June 14, hit back at Gibbons' claims. "We did everything we could," Warren said. "What they didn't tell us was that they had just made the application. They completely messed up. The real losers are myself and Alex Arthur."

n Paulie Malignaggi, the IBF light-welterweight champion, has been told to forget any fight with Ricky Hatton until he has dealt with Lovemore N'dou in their rematch in Manchester on May 24.

Malignaggi failed to impress in his first defence of the IBF belt in Atlantic City in January, labouring to a unanimous, though less clear-cut, decision over number one contender Herman Ngoudjo (16-1) - and McGirt believes that was because of the Hatton talk.

"Paulie won't be looking ahead to Hatton," said McGirt.
