Who is the "mystery " December opponent for Mayweather?

[Shabba Rank$]

I have a strong feeling that it will be Martinez.

That racist avatar you have there is just sickening.

[sicko]

don't believe the Smoke Screens, Manny vs Mayweather will happen

[Pacquiao'd]

I have a strong feeling that it will be Martinez.

change your avatar or get reported for racism

He definetly wouldnt fight Margarito after the hand-wraps situation. HBO promotes Floyd to the max and I know for sure that HBO will never put Margarito on their network again.

Erik Morales.

No way it will be S. Martinez or Pacquiao. Speculation is it will be Saul Alvarez or Erik Morales.

[BrooklynBomber]

He will bring Prince Naseem out of retirement and fight for the vacant 154 pound belt.

[F l i c k e r]

Amir Khan.

If the Manny/Floyd fight fails to pull through I can't see Floyd attempting to fight any Top Rank fighter, that said, that excludes Cotto or Margarito.

Somebody already mentioned the Al Haymon connection with Berto and Floyd so that may never take place either. Besides, Berto doesn't have much of a following and hasn't fought any elite fighter worth a PPV fight for Floyd.

This leaves one of two fighters, the aforementioned Sergio Martinez (in which Floyd mentioned he'd fight after the Mosley fight) Or Bradley.

Martinez or Pac. Otherwise retire.
