A couple of Twitter barbs have "sparked" the conversation of a potential fight between Conor McGregor and Kamaru Usman.
While the fight is unlikely to be booked, SportsBetting.ag has set odds on the bout just in case McGregor wants to test his mettle in the 170-pound weight class.
And according to the oddsmakers, McGregor would find himself the biggest underdog in any fight of his career.
