Floyd Mayweather Jnr has hinted that he may give up boxing earlier than originally planned.
"There really isn't anybody out there for me to fight," Mayweather told boxingscene.com. "So I really don't know where my career is going to go from here.
"There is nothing [left] but the young pups, the strong young pups coming up. And they are probably going to try to build a young guy [for a fight with me].
"I've been feeling like [I wanted to retire] before this fight. Like I said before, if it is my last my fight at least I gave the fans [what they wanted]."
The 35-year-old, who begins a 90-day prison sentence for assault on June 1, recently claimed that he would wait two years before hanging up his gloves.
