Mayweather Marquez Fight Preliminaries

Alhough Floyd Mayweather Jr. is undefeated, he still has a lot to prove Saturday night in Las Vegas. Mayweather, who last fought December 2007 vs Ricky Hatton, must show against Juan Manuel Marquez that his boxing skills are still there.

Meanwhile, Marquez has been in plenty of battles in the past 18 months. He lost a controversial split decision in a rematch with Manny Pacquiao, stopped the well-regarded Joel Casamayor and rebounded to stop Juan Diaz to win the lightweight title.

Despite the fact that Marquez and Mayweather are considered very smart, technical fighters who can make adjustments during the fight, many boxing critics are saying that the tempo of the fight will be determined in the first few rounds.
