UFC matchmakers will have a long list of fighters to choose from when they begin putting together the fight card for the next year’s UFC event at the White House.  Several high-profile fighters on the fight promotion’s roster have requested to be part of the fight card, and former champions have expressed the willingness to come  out of retirement  to compete at the event.  UFC CEO  Dana White would like  Conor McGregor to  headline . Former two-division champion  Jon Jones has all but begged to be featured. On Monday, former bantamweight champion  Sean O’Malley threw his name in the hat.
