Manny Pacquiao and Timothy Bradley are just days away from stepping in the ring at the MGM Grand Garden Arena in Las Vegas, Nevada.

The boxers will face off on Saturday, June 9 with the WBO Welterweight title on the line.

It's the first time that either Pacquiao or Bradley will fight in 2012. Pacquiao is 54-3-2 is his career, while Bradley has yet to lose a fight.

Oddsmakers seem to think Bradley's record will no longer be perfect after this weekend. According to the online sportsbook Bovada, Pacquiao is a heavy favorite to come out victorious.

The site sets his odds of winning at minus 450. Bovada puts Bradley's odds at plus 325.

The fight is expected to go all 12 rounds, with no knockout either way. The odds of Manny Pacquiao winning by decision or technical decision are set at plus 110.

Pacquiao has 38 knockouts in his career. Bovada has put the odds of him winning by KO, TKO or DQ at minus 160.

The least likely outcome, according to the site, would be a draw. Betting $100 would net a person $2500 if the fight ends without a winner.

The over/under for the fight is set at 9.5 rounds. The odds favor the fight going at least 10 rounds. You would have to bet $280 to win $100 on that wager.

The odds of the fight going fewer than 10 rounds are set at plus 190.
