It took more than five years to finally get Floyd Mayweather and Manny Pacquiao to agree to square off in the biggest fight to be made in recent history. May 2 is still more than a week ahead, yet some have already begun to wonder what lies ahead for both fighters.

Recent declines in pay-per-view sales for both fighters clearly indicated they needed this fight to happen now. Still, in the event that they once again headed in opposite directions, Mayweather had a few more options than Pacquiao in terms of possibly selling the public on a contingency plan.

Amir Khan is the name most often mentioned, and for each of the past two May dates was in the running for a Mayweather showdown. The former 140 lb. titlist was believed to be the front runner for the most lucrative assignment in the sport last May, but the fight instead went to Marcos Maidana.

One year later, Khan was back in the hunt only for the long awaited showdown with Pacquiao finally materializing. There’s an outside chance he could serve as Mayweather’s final opponent, which the pound-for-pound and box-office king insists will take place in September.

Any such discussion, however, remains purely speculative. For now, the goal is to get through May 2, when the two meet live on Pay-Per-View from the MGM Grand in Las Vegas, Nevada.

“My focus is on this fight,” insisted Mayweather (47-0, 26KOs) - who is guaranteed a record $120 million for the fight – when asked during a recent media conference call about the possibility of facing Khan in the future. “My last fight is in September. I can’t say whom I’m going to fight in September.

“I’ve never been one to overlook anybody. I take it one fight at a time. Right now, Manny Pacquiao is the one that’s in front of me. That’s my focus.”
