An injury has caused yet another change to a scheduled UFC co-main event.

Roan Carneiro (20-9 MMA, 3-3 UFC) is unable to compete in his slated bout against Gegard Mousasi (37-5-2 MMA, 4-2 UFC) at UFC Fight Night 75. Uriah Hall (11-5 MMA, 4-3 UFC) will step in to face Mousasi in the middleweight co-headliner in Japan.

UFC officials announced the switch Wednesday evening.

UFC Fight Night 75 is scheduled for Sept. 26 at Saitama Super Arena in Saitama, Japan. The main card airs on FOX Sports 1 following prelims on the same channel and UFC Fight Pass.

Carneiro has not competed since a first-round submission of Mark Munoz at UFC 184 in February. It was his return to the organization after more than six years and “Jucao” earned a win that put him on the radar at 185 pounds.

The Brazilian was forced to undergo elbow surgery following the memorable win. It’s unknown if the latest injury is related to the surgery.

Mousasi has been no stranger to replacement opponents throughout his 44-fight career. “The Dreamcatcher” has managed to make it work, though, because he’s currently on a two-fight UFC winning streak with impressive performances against Costas Philippou and Dan Henderson.

The former Strikeforce and DREAM champion has not competed in Japan in more than five years and UFC Fight Night 75 will mark his first contest in the country since July 2011.

Hall will look to spoil Mousasi’s return to “The Land of the Rising Sun,” and in the process, earn the most significant victory of his career.

“The Ultimate Fighter 17” runner-up is fresh off a first-round TKO of Oluwale Bamgbose at UFC Fight Night 73 earlier this month and will look to win for the fifth time in his past six UFC appearances at the expense of Mousasi.
