The Floyd Mayweather vs. Shane Mosley boxing match is expected to be a blockbuster despite the older Mosley coming into the ring at age 38.  The fight will come as the main event of the card which starts at 9 PM ET from the MGM Grand Garden Arena in Las Vegas.

Mayweather will bring his 40-0 record into the ring and prove that he is once again the world’s best poind for pound fighter.  Of those 40 wins, 25 have come by way of knockout for the 147 pound champion.

Mosley is a decorated boxer coming in with a 46-5 record to Saturday’s fight with Mayweather.  Impressively he has 39 wins by way of knockout which is far more than Mayweather.  But his age could be a factor as he is five years older.

Mayweather comes from a family of boxers as his father was a professional fighter.  His uncle Roger was a champion twice and also another uncle was a professional boxer.

Mosley is a two time welterweight champion and a three division champion.
