LAS VEGAS (AP) -- MGM Mirage Inc.'s chairman and chief executive said Tuesday the company expects within two weeks to sell one of two casinos in Detroit.

Terry Lanni's comments came as Nevada gambling regulators recommended approval for MGM Mirage to buy rival Mandalay Resort Group and create one of the world's largest gambling companies.

MGM Mirage owns the MGM Grand casino in Detroit, and Mandalay is majority owner of the city's MotorCity Casino. Michigan law requires casinos to be owned separately.

Lanni did not say which casino would be sold.

Combining the Las Vegas-based companies would give MGM Mirage revenues of about $6.5 billion and control of 28 properties in Nevada, Illinois, New Jersey, Michigan and Mississippi.

Lanni said Tuesday the company was seeking required regulatory approvals in the other states. Mississippi approved the deal in December.

MGM Mirage stock closed Tuesday at $75.05 per share, down $3.45 on the New York Stock Exchange. Mandalay Resort stock closed at $70.68, up 2 cents.
