If Pacquiao suffered the cut in November it should be easily healed by now if he didn't get an antibiotic resistent infection.
Doesn't really look like those two guys are ever fighting against each other.
In that case it came down to money. I really hoped they would fight before Mayweather went to jail. That could mess up his career. I'm sure Manny isn't afraid Floyd but i think Arum is scared shitless.
