Unbeaten five-division titleholder Floyd Mayweather Jr. will be a guest on the Conan O'Brien Show on Monday night on the TBS network to tout his challenge of WBC welterweight titleholder Victor Ortiz that will take place on HBO Pay Per View from the MGM Grand in Las Vegas on Saturday.
Another guest on the show will be comedian Howie Mandel, who is also serving as a judge on "America's Got Talent."
Mayweather's appearance is part of a massive advertising and promotional campaign during which Time Warner is employing a number of its assets.
They include Turner Broadcasting's TBS, TNT, CNN, the latter of which recently aired Ortiz and Oscar De La Hoya together on "Piers Morgan Tonight."
