Tonight beginning at 6 pm ET with the preliminary bouts and 9 pm ET for the four-fight main card, BLH will be here with live updates for the full Pacquiao-Vargas event on pay-per-view, live from the Thomas & Mack Center in Las Vegas.

Manny Pacquiao (58-6-2, 38 KO) headlines the night in a challenge for the WBO welterweight title, facing titleholder Jessie Vargas (27-1, 10 KO) in a 12-round main event. The 37-year-old Pacquiao last fought in April, defeating Timothy Bradley Jr, while Vargas is coming off of a dominant win in March over Sadam Ali.

The pay-per-view undercard, in running order, will feature three more WBO world title fights. At flyweight, Shiming Zou (8-1, 2 KO) takes on Prasitsak Phaprom (39-1-2, 24 KO) for the vacant title, in a rematch of a fight Zou won handily in 2014. At super bantamweight, Nonito Donaire (37-3, 24 KO) defends against unbeaten but untested Jessie Magdaleno (23-0, 17 KO). And at featherweight, exciting young Oscar Valdez (20-0, 18 KO) makes a defense against Hiroshige Osawa (30-3-4, 19 KO).

The preliminary bouts will feature pro debuts for two 2016 Olympians. Gold medalist Robson Conceição of Brazil will be in action, as will American Teofimo Lopez Jr, who fought for Honduras in Rio.
