LAS VEGAS -- Manny Pacquiao is due to arrive in Las Vegas Monday night, five days before his highly anticipated bout with WBO welterweight champion Miguel Cotto at the MGM Grand.

Pacquiao, known as the “Fighting Pride of the Philippines,” last set foot in the ring back in May, when he floored Ricky Hatton and won the IBO and Ring Magazine Light Welterweight titles in front of a packed house at the same venue.

During that fight, Hatton was knocked down twice in the first round and sent to the mat for the final time at 2:59 into Round 2.

Saturday’s fight has been described as one of the biggest in Pacquiao’s career, as well as a financial gold mine. The 30-year-old is expected to get a much larger share of Pay-Per-View revenues than Cotto.

It is also likely to be a major draw for tourists, although the Las Vegas Convention and Visitors Authority does not project revenues for fight weekends.
