One of the most famous clips in boxing history, 2 of the all time greats, 2 for sure future hall of famers & probably the best knockout in all modern history in combat sport. A tremendous fight where Pacquiao & Marquez would trade knockdowns, hurt each other along the way before Marquez unleashed a devastating overhand right to Pacquiao's face at the bell of round 6 that put PacMan flat on his face.
