After an illness scratched Ruslan Magomedov from UFC 204, Daniel Omielanczuk has agreed to step in as a replacement and fight Stefan Struve at UFC 204.

The news was confirmed to MMAjunkie by a person close to one of the fighters. The person requested anonymity because UFC officials haven’t formally announced the bout.

Magomedov (14-1 MMA, 3-0 UFC), who’d won three straight in the UFC, was diagnosed with staph infection.

UFC 204 takes place Oct. 8 at Manchester Arena in Manchester, England. The main card, including middleweight champion Michael Bisping vs. Dan Henderson, airs on pay-per-view following prelims on FS1 and UFC Fight Pass.

The bout order hasn’t been finalized, but Struve (27-8 MMA, 11-6 UFC) vs. Omielanczuk (19-5-1 MMA, 4-2 UFC) is expected to be on the main card.

Struve hopes to build on a 16-second knockout victory in his previous appearance at UFC Fight Night 87. The 6-11 fighter toppled onetime title challenger Antonio Silva, reversing a downward trend after a lackluster decision loss to Jared Rosholt at UFC 193 that left him 1-3 in his previous four outings.

After a rocky 1-2 patch, Omielanczuk is trending up with three straight wins, including a recent majority decision over Oleksiy Oliynyk, who’d previously won back-to-back UFC bouts and nine straight fights on the international circuit.
