WBO welterweight champion Timothy Bradley is expected Manny Pacquiao to be very eager, and very aggressive, while hunting for a knockout victory in their rematch on April 12th at the MGM Grand in Las Vegas. In June of 2012, Bradley won a controversial twelve round split decision over Pacquiao.

Bradley says Pacquiao career is now at the brink. He was knocked out in six rounds by Juan Manuel Marquez in December 2012, and then came back to win a twelve round decision over Brandon Rios last November.

"He hasn't lost his gifts at all, but I think his killer instinct is gone. I'm a lighter puncher than Rios. Rios is a bigger puncher. The first time around he was very defensive when I fought him. I think he's going to fight differently. I think he's at a point in his career where it's do or die for him. A loss for Manny right now, I don't know if it would end his career because the people love him - but it wouldn't be good for him, it would be bad," Bradley said.
