MGM Grand, Las Vegas - "Sugar" Shane Mosley does not consider Manny Pacquiao a "small welterweight." He says Pacquiao is just as big, and strong, as any other welterweight opponent that he's faced in his career. Mosley challenges Pacquiao for the WBO welterweight title on Saturday night at the MGM Grand in Las Vegas.

Mosley says that he won't make the same mistake as some of Pacquiao's past opponents, by looking at the Filipino boxer as if he's a "small guy."

"Pacquiao has been fighting at welterweight and he also had one fight at junior middleweight. Pacquiao is a short welterweight, but he's not a small welterweight. He's very strong. It's like Mike Tyson who fought all of these big heavyweights. I'm just looking to go out there and take charge and beat Manny Pacquiao," Mosley said.
