Ultimate Fighting Championship (UFC) has requested the dates of May 26 and July 7 for its upcoming pay-per-view (PPV) events at the MGM Grand Garden Arena in Las Vegas, Nevada, according to an Email sent to MMAmania.com from NSAC Executive Director Keith Kizer earlier today. Both events coincide with holiday weekends (Memorial Day and Fourth of July, respectively) with the latter being the send-off for the UFC's 2012 Fan Expo. And preliminary guesses as to possible event headliners? Junior dos Santos vs. Alistair Overeem? Anyone?
