Former interim UFC lightweight champion Tony Ferguson has challenged former two-division champion of the promotion Conor McGregor.

"Unfinished Business. Where are you, McNuggets?" Ferguson wrote on Instagram.

The 37-year-old Ferguson is on a streak of three straight losses. The American had his last fight on May 15, losing by unanimous decision to Beneil Dariusz.

McGregor, 33, is also having a rough time in his career, losing three times in his last four fights. On July 10, the Irishman lost by TKO to Dustin Poirier, breaking his leg in the first round.
