Eight division world champion Manny Pacquiao (54-5-2, 38KOs) is not stressed out over his sixth round knockout loss to Juan Manuel Marquez (55-6-1, 40KOs) from last December in Las Vegas. In their fourth and most brutal fight, the two boxers exchanged knockdowns in the earlier rounds - but Marquez landed a perfect counter in the close seconds of the sixth round. That final blow as all Marquez needed. Pacquiao was knocked unconscious and went down face first.

Pacquiao returns on November 23rd against Brandon Rios, while Marquez challenges WBO welterweight champion Timothy Bradley on October 12th.

"It's part of boxing....sometimes you lose and sometimes you win - and I think [Marquez] just got lucky, he got a lucky break in that fight. I feel good and I'm ready to fight Rios. He likes to fight toe to toe so it will be exciting ," said Pacquiao.
