Amir Khan's hopes of agreeing a deal to fight Floyd Mayweather Jr have been eased after the Briton revealed he has split with Golden Boy Promotions and Showtime Television, extinguishing the legal obstacles that forced him to reject a meeting with Manny Pacquiao.

Khan is now free to liaise with alternative promoters in the search of career-defining bouts in the future but appears likely to allow Oscar de la Hoya, the Golden Boy chief, to continue to represent him.

Top rank chief-executive Bob Arum claimed last week that the 28 year old has been forced to turn down a fight with Pacquiao due to contractual obligations but those restraints have been relinquished allowing Khan to continue his pursuit of Mayweather.

"I need to see what's going on with these superfights," Khan said after defeating Devon Alexander via a unanimous points decision in Las Vegas.

"I'm going to hopefully find out in the next couple of weeks when I sit down with Al Haymon [Khan's adviser] and Golden Boy.

"I've sent a statement that I'm a major force at 147[lb, his weight division] and am one of the top guys in this division. I'll see where the path takes me.

"I don't want to miss my chance to fight Floyd Mayweather or Manny Pacquiao. If I take the Kell Brook fight, they might retire. This might be Floyd's last fight. You don't know when they might call it a day."

The British fighter's hopes of securing a meeting with Mayweather have taken a slight blow, however, after the unbeaten American admitted tentative talks have begun with Pacquiao for a prospective duel on 2 May.

"Floyd just likes to mention names," Khan added. "We'll see. I'll just leave it to my team. I've had calls from Michael Koncz, who is Manny Pacquiao's business manager and he asked me if I would be interested in the Pacquiao fight.

"But I hope the fight with Mayweather and me does happen. He wanted me to prove myself and I think I've done that now. It has to happen now.

"Does Pacquiao want to fight him? I don't know. Is he [Pacquiao] going to do the drug testing? I don't know. I think Floyd Mayweather is just using it to get to me and get in my head. He's just trying to disrupt me."
