In Dec. 2015, Conor McGregor knocked out then-Featherweight champion, Jose Aldo, in 13 seconds at UFC 194 to claim the 145-pound crown. It was the fastest knockout in UFC championship fight history. And "Notorious" has not returned to the division since, splitting a pair of back-to-back Welterweight bouts with Nate Diaz and now negotiating a deal to headline UFC 205, which takes place inside Madison Square Garden in New York, N.Y., on Nov. 12, 2016, opposite Lightweight champion, Eddie Alvarez. There has never been a current dual weight class champion in UFC history. Randy Couture and B.J. Penn have held belts in two different divisions, but never at the same time.
