Rampage has already signed his side of the bout agreement according to a recent report from Yahoo! Sports.
The fight was originally scheduled to take place at UFC 98, then UFC 107, but Rampage participation in the upcoming the A-Team movie caused the delay.
The Evans and Jackson rivalry heated up when both fighters were coaches on the previous season of The Ultimate Fighter.
This will be Jackson’s first fight in nearly a year when he picked up a victory of perennial contender and Evan’s teammate Keith Jardine at UFC 96, while Evan’s was last seen edging out a decision victory over Thiago Silva lost after losing the belt to Lyoto Machida last May.
UFC 114 takes place on May 29 with a light heavyweight bout between Forrest Griffin and Antonio Rogerio Nogueria also taking place on the card.
