Joan Guzman has dropped the WBO super featherweight title in a bid to move up weight to tackle the reiging lightweight champion Nate Campbell and in effect canceling the scheduled matchup with Alex Arthur in May. Promtping Guzman's rise in weight, Alex Arthur had now become the WBO super - featherweight champion.

Joan Guzman had the following to say to Nate Campbell

"I think Nate Campbell would be a perfect opponent for me," said Guzman, who is a two-division champion with a record of 28-0, 17 KOs. "Nobody wants to fight Nate at 135 pounds and no one wants to fight me at 130 pounds. So let's just fight each other....If Nate is truly a world champion he will accept the challenge that I have laid out for him."

Arthur had been the 'interim' champion after beating Koba Gogoladze in July.

"I'm delighted with the decision by the WBO to give me full world champion status but I felt that I won the title when I beat Gogoladze," said Arthur.

"I'm confident that I would have beaten Guzman had the fight been rescheduled but I believe that I am among the elite super-featherweights and want to prove myself as the best out there.

"I'm proud to be Edinburgh's first world champion for 30 years, and am looking forward to making the first defence of my title. My reign begins now."

Promoter Frank Warren said he expected Arthur to be a "long-term world champion".

He added: "I'm working hard at the moment to deliver a new date and challenger for Alex."

When Arthur was named the WBO's interim champion it effectively meant he was considered the organisation's number one contender.
