The Jon Jones vs. Rashad Evans showdown is finally official for UFC 145 on April 21 in Atlanta.

UFC president Dana White on Monday confirmed the bout and tickets for the event at the Phillips Arena will go on sale Feb. 17.

Evans won the light heavyweight title shot by beating Phil Davis two weeks ago at UFC on FOX 2, setting up the much-delayed meeting with his rival, the UFC champion Jones. Jones will be returning from a brief vacation after defeating Lyoto Machida at UFC 140 in December.

On Monday, Jones' coach Greg Jackson said he was still unsure if he would corner Jones against Evans due to Jackson's personal connection with Evans. Evans made his rise in MMA through Jackson's gym, but eventually left when it became clear he and Jones would inevitably meet inside the UFC cage.
