A rematch of the most important fight of Season 21 of “The Ultimate Fighter” has been booked for the UFC’s return to Florida in December.

Hayder Hassan (6-2 MMA, 0-1 UFC), from American Top Team, will meet the Blackzilians’ Vicente Luque (7-5 MMA, 0-1 UFC) in a welterweight bout at UFC on FOX 17. UFC officials announced the fight booking after an initial report from the South Florida SunSentinel.

UFC on FOX 17 takes place Dec. 19 at Amway Center in Orlando. The event’s main card airs live on FOX following expected prelims on FOX Sports 1 and UFC Fight Pass. UFC on FOX 17 is headlined by a lightweight title match between champ Rafael dos Anjos and Donald Cerrone.

On “TUF 21,” Hassan beat Luque by split decision on the show’s final regular-season episode, giving ATT a come-from-behind victory in the team-vs.-team competition.

Hassan was chosen by his team to fight for the “TUF 21” crown at the live finale in Las Vegas. But there, he was submitted by the Blackzilians’ Kamaru Usman in the second round of his official UFC debut. Now he’ll try to get his first official win for the promotion against Luque. Prior to the loss in July, Hassan was on a four-fight run, including three wins by knockout.

Despite losing to Hassan in their pivotal end-of-the-season bout, Luque got a shot at the TUF 21 Finale, anyway. But there, he dropped a unanimous decision to Michael Graves. Prior to that, he had won three of four fights before signing on for “TUF 21,” and overall, six of his seven wins are by stoppage.

With the addition to the card, UFC on FOX 17 now includes:

Champ Rafael dos Anjos vs. Donald Cerrone – for lightweight title Junior Dos Santos vs. Alistair Overeem Nate Diaz vs. Michael Johnson C.B. Dollaway vs. Nate Marquardt Tamdan McCrory vs. Josh Samman Danny Castillo vs. Nik Lentz Hayder Hassan vs. Vicente Luque
