Mayweather vs. Berto: Weigh-in Results, Odds, Fight Time and Undercard Info

We're all set for what is supposed to be Floyd Mayweather Jr.'s last dance in the ring, Saturday night against overmatched contender Andre Berto in a welterweight title fight.

Both boxers made the weight in Friday's weigh-ins comfortably, as Mayweather clocked in at 146 pounds and Berto just one pound lighter. Appearing confident and borderline cocky on the stage against a boxer who's never lost, Berto doesn't seem to be shying away from the spotlight.

There's a packed slate of undercard bouts leading up to Mayweather-Berto, so let's take a closer look at them while assessing the main event odds.

Could we see the final chapter in one of the greatest careers in boxing history Saturday night?

It may be too early to tell for sure, in fact it surely is, but that's what the Mayweather camp is saying as things gear up for the bout with Berto. According to them, the pound-for-pound king is going to hang up the gloves for good once he presumably wins his 49th fight.

As things gear up for fight night, that tune has not changed among Mayweather and his comrades, as ESPN's Darren Rovell noted:

There are more than a few reasons why Mayweather would be compelled to step back into the ring. First on the list is the potential of improving his record to 50-0, which would propel him past Rocky Marciano's record.

Also, there's the chance that the winner of Miguel Cotto and Saul "Canelo" Alvarez's bout in November could push his way into contention to fight Mayweather. It's hard to believe that he would pass up the millions upon millions that would come from such a fight.

With that said, Mayweather has his own plans for money-making after his boxing days, as ESPN's Dan Rafael noted:

"

"I received three major movie offers [recently], so we fully expect that Floyd could be heavily involved in the entertainment industry because this is what he does," (Mayweather Promotions CEO Leonard) Ellerbe said. "I know for a fact that with the significant entertainment offers coming our way that it's definitely something that is going to occupy a lot of his time."

"

Before Mayweather can worry about entertaining folks on the silver screen, however, he'll have to figure out a way to entertain them one last time in the ring. In a fight that doesn't have quite the same amount of sizzle as his previous encounter with Manny Pacquiao, that will be a central theme.

It's questionable in the first place as to why Mayweather took this fight, against an opponent who is just 3-3 in his last six fights and has struggled to stay near the top of the weight class. Whether he has the power and speed to be able to fluster Mayweather remains to be seen.

There's no telling right now if the talk from Mayweather's side of things is legit or if there are plans for more fights in the future. But with the way they're talking, the last chance to see Money May in action just might be this weekend.
