Derby entrant Itsaknockout touts Mayweather-Pacquiao fight (The Associated Press)

The estranged worlds of horse racing and boxing will cross paths at the Kentucky Derby. The race and Floyd Mayweather-Manny Pacquiao welterweight championship fight are on Saturday, and owners of Derby entry Itsaknockout are capitalizing on a cross-promotion opportunity. Starlight Racing has agreed to a sponsorship deal with promoters of the blockbuster title fight. Itsaknockout will wear a ”Mayweather vs. Pacquiao”-branded blanket when he’s not training.
