RFA and “The Ultimate Fighter 22” vet Jason Gonzalez is headed to the big show after a training injury scrapped Erik Koch from next month’s UFC 203, the promotion announced today.

Gonzalez (10-2 MMA, 0-0 UFC) will face off with veteran Drew Dober (16-7 MMA, 2-3 UFC) at the Sept. 10 pay-per-view event, which takes place at Quicken Loans Arena in Cleveland. The fight card’s official order has yet to be announced. Preliminary card bouts can been seen on FS1 and UFC Fight Pass.

It’s the second time a bout between Dober and Koch (15-4 MMA, 4-3 UFC) has been scrapped due to an injury to Koch.

Gonzalez enters the octagon on a six-fight winning streak. He made it into the house on “TUF 22” only to be outpointed in the reality show’s quarterfinal round by Abner Lloveras. Most recently, he caught the UFC’s eye again when promotion president Dana White attended RFA 38 to film “Dana White: Looking for a Fight” and he picked up a second-round TKO over Chris Padilla.

Opposite the cage on Sept. 10 is Dober, who in January got back in the win column with a decision over Scott Holtzman at UFC 195. Now seven fights into his UFC tenure, Dober has had a rocky go of things, suffering a submission loss to Leandro Silva that was ultimately overturned due to referee error and, prior to Holtzman, submitting to a standing guillotine at UFC 188.

With the change to the card, UFC 203 now includes:

Stipe Miocic vs. Alistair Overeem

Fabricio Werdum vs. opponent TBA

Nik Lentz vs. Mairbek Taisumov

Damir Hadzovic vs. Yukawa Kazuya

Mickey Gall vs. CM Punk

Bethe Correia vs. Jessica Eye

Urijah Faber vs. Jimmie Rivera

Jessica Andrade vs. Joanne Calderwood

Ray Borg vs. Ian McCall

Caio Magalhaes vs. Brad Tavares

Drew Dober vs. Jason Gonzalez
