Watch Manny Pacquiao vs Chris Algieri Live Stream Online Free Full Fight Video

Tonight at 9:00 pm EST on HBO pay-per-view, BoxNation, and a host of other channels worldwide, Manny Pacquiao headlines again in Macau against Chris Algieri, with the WBO welterweight title on the line for the 144-pound catchweight bout.

Pacquiao (56-5-2, 38 KO) is the heavy favorite as usual, with the little-known Algieri (20-0, 8 KO) receiving minimal respect as a real threat to the Filipino superstar. But the fight has a potentially intriguing style clash, as the younger, fresher Algieri is also the much taller man, and could use his length to dictate the range of the fight behind his jab. This is no gimme for Pacquiao, and it's a must-win for him, and a huge opportunity for Algieri.

On the undercard, Zou Shiming (5-0, 1 KO) will face Kwanpichit OnesongchaiGym (27-0-2, 12 KO) in a 12-round flyweight bout; Vasyl Lomachenko (2-1, 1 KO) defends the WBO featherweight title against Chonlatarn Piriyapinyo (52-1, 33 KO); and Jessie Vargas (25-0, 9 KO) will put his WBA paper belt on the line against former lightweight titlist Antonio DeMarco (31-3-1, 23 KO) in a 12-round junior welterweight fight.
