BEVERLY HILLS, California - Three compelling fights in eight years haven't resolved the rivalry between Manny Pacquiao and Juan Manuel Marquez, so they're stepping in the ring together for a fourth bout on December 8 in Las Vegas.
This time, they're both looking for knockouts, settling their score once and for all.
They fought to a draw in 2004, and Pacquiao won by decision in 2008 and again last year.
Marquez and many fans still believe he won all three fights, while Pacquiao says he clearly won the last two.
Marquez says the only way to be sure he'll finally get his hand raised is to stop the Filipino congressman.
Coming off his first loss since 2005, Pacquiao says he's going back to the ferocious, brawling style that made him an eight-division champion.
