Undefeated middleweight Bo Nickal faced the biggest test of his young MMA career when he met Reinier de Ridder in the co-main event for UFC Des Moines.
One of the most highly-touted prospects in the history of MMA, Nickal stopped the first three opponents he faced after joining the UFC before going the distance against Paul Craig at UFC 309 last November.
De Ridder also entered UFC Des Moines with an unbeaten Octagon record, as the former ONE Championship star debuted with a submission-win against Gerald Meerschaert last year before he made short work of Kevin Holland at UFC 311.
Despite de Ridder's sizeable edge in MMA experience over Nickal, the 34-year-old entered UFC De Moines as one of the bigger underdogs on the card.

It didn't take long for the significantly larger de Ridder to initiate a clinch before he was forced back to the cage, and after an extended period where both men fought for position it was Nickal who managed to bring things to the mat.
A submission attempt from Nickal allowed de Ridder to scramble into top position before the two men returned to their feet in the final seconds of the first round. The second frame once again opened with an extended clinch on the fence, but after the pair moved to the center of the cage "RDR" landed a couple of solid knees that appeared to rattle his opponent.
Sensing that he had Nickal hurt, de Ridder began to apply pressure and continue landing knees until a perfectly-placed shot to the body folded Nickal to give the formerly-undefeated fighter his first MMA loss and add to the Dutch middleweight's perfect UFC record.
