Although Timothy Bradley Jr. may not pop out as a household name, don't expect him to go down so easily against WBO Welterweight champion Manny Pacquiao.

Pacquiao, 33, has been under heavy pressure after producing mediocre victories over Shane Mosley and Juan Manuel Marquez.

He has not solidified a knockout since 2009, and barely scrapped up a win over Marquez on Nov. 12.

I was in 100 percent physical condition for that fight against Marquez, but I did have some family issues that I had to deal with, Pacquiao said. I also underestimated him.

Now a congressman in the Philippines, Pacquiao admits that the pressure is on to perform at a high level to regain his stature as a cunning fighter.

I like to give a good show to the people and make people happy, Pacquiao told reporters. I always pray this fight will be a good fight and people will be satisfied.

Bradley, on the other hand, is not buying into all the hype.

I'm ready to dethrone the Pac-Man, Bradley said. I'm ready 110 percent. Without a doubt on my mind, there's no doubt in my bones.

Despite the fight being set for Saturday night, Pacquiao arrived early in Las Vegas to get some last minute workouts in.

Within hours of arriving from his flight, Pac-Man hit the track at the University of Nevada in Las Vegas for his annual run before greeting fans at the MGM Grand.

I don't know what Bradley will bring in the ring on that night, but we will be ready for whatever he brings, Pacquiao said. Bradley is a different type of fighter and we don't take this fight lightly. We have trained hard for Bradley because he is the type of fighter we cannot underestimate.

Pacquiao is expected to make around $26 million for the fight, while Bradley is guaranteed at least $3 million.

The fight at the MGM Grand Garden Arena in Las Vegas is set for June 9.
