Jon Jones and Alexander Gustafsson 2 is set for September 27.
The rematch bout will be during UFC 178 in Toronto, Canada.
Jones won a unanimous decision against Gustafsson at UFC 165 in September 2013.
Jones, 26, is 20-1 in the MMA. His last fight was a win over Glover Teixeira at UFC 172 in April.
Gustafsson, 27, is 16-2 in MMA but has only fought once since fighting Jones. He beat Jimi Manuwa in March of this year.
Jones issued a statement.
“There was never an issue with a contract. I was traveling and finally got to Vegas and got to talk with Dana and Lorezno. We talked and September 27th, I’ll be fighting Gustafsson,” Jones said via release. “I think Cormier is the tougher fighter, but the fans want to see me fight Gustafsson. There was never an issue with taking the Gustafsson fight,” Jones said in a press release.
“The issue was that my brother is getting married in July and I would have preferred a later date. I didn’t want to go this early and i would have preferred to go later in October or November. It is what it is. We have a date now, Sept 27th. This was a personal decision for me. I will be at my brother’s wedding and have a proper training camp.”
“Obviously Jon is right, this if the fight the fans want to see. The great thing about this is, we get Jones vs Gustaffson, and if Jones beast Gustafsson, we get Jones vs Cormier. Two great fights in the light heavyweight division with three of the baddest guys in the world: the pound-for-pound best fighter in the world and champion Jon Jones, and the number one and two contenders,” UFC President Dana White added.
