Pre-fight coverage, undercard rundown, and more after the jump.

Chavez Jr (46-0-1, 32 KO) and Martinez (49-2-2, 28 KO) are meeting in one of the year's most highly-anticipated fights, and a rarity in modern boxing as this became a big fight naturally, was "marinated" just the right amount of time, and right when it was really begging to be made, it actually got made. If this happened more often, we'd have unicorns. In the real world.

Guillermo Rigondeaux (10-0, 8 KO) vs Robert Marroquin (22-1, 15 KO)
