Marinez says he'll come down to 154 to fight Floyd but Martinez is busy until next year. This year Floyd actually looks like he'll fight Guerrero and Canelo. Bradley is the only other serious option for the first fight but he's just about to sign to fight somebody else. And Schaefer says he's doing the Guerrero/Canelo contracts all at the same time as Canelo wants it in writing that he gwets the Mayweather fight before he agrees to be on the same bill/PPV.
So if Floyd announces a fight against Guerrero/somebody else but not against Canelo then you know the Canelo fight isn't happening, at least right now. I think they'll both get announced soon though. After the Superbowl is over probably.
