UFC on Fox is a major milestone for MMA, and it could be a huge catalyst that propels the sport into new heights. Velasquez vs. Dos Santos is an excellent match up, but that being said, it definitely won't be the biggest combat sports event on that day. That honor belongs to boxing's mega-fight between Manny Pacquiao and Juan Manuel Marquez, the final bout of their trilogy that has already produced two classic bouts.

As they tipped the scales, both fighters came in below the 144 lb. limit, with Pacquiao coming in at 143, and Marquez at 142 lbs.

Most MMA fans will surely catch the UFC on Fox event, but the option of watching both major fights is available as the two superstars from boxing will meet about an hour after the Cain Velasquez vs. Junior Dos Santos broadcast ends.
