Mayweather yet to contact Maidana as Khan remains favourite for May 3

A potential welterweight unification clash between current WBC title holder Floyd Mayweather Jr. and WBA champion Marcos Maidana is looking increasingly unlikely as Amir Khan edges closer to sealing a May 3 encounter

Rumours have been circulating that Maidana may have gone ahead of Khan in the race to snare a mega-contract to face Mayweather, although WBN can confirm that no contact has yet been made with the Argentinian.

Sebastian Contursi, advisor to Maidana, has told World Boxing News that there has been no effort from Mayweather Promotions to spark up negotiations, meaning an imminent announcement is impossible.

Mayweather is said to be close to confirming his 46th opponent for his upcoming spring date in Las Vegas, Nevada and Briton Amir Khan still looks odds-on to land the big-money Showtime PPV deal.

Fans have not reacted well to a possible Mayweather v Khan extravaganza at the MGM Grand, with most plumping for Danny Garcia, Tim Bradley or Maidana himself as more exciting opposition.

In saying that, Khan does possess blistering hand speed, something that Mayweather has seldom faced in his recent past, and has had plenty of time since his last fight to prepare himself for what will be his biggest challenge.

At this point in time, Khan seems more than a certainly to get the nod as a fight with Manny Pacquiao once again gets brushed aside and Mayweather begins preparations to add another hefty sum to his already bulging bank balance.
