Just when we thought Elvis Brener vs. Esteban Ribovics brought fire at UFC Vegas 108, one fight later and we got another war of attrition that saw Chris Duncan defeat Mateusz Rebecki in the evening's co-main event.

Round one was a chaotic slugfest, with both men trading huge shots early. Rebecki dropped Duncan briefly and landed powerful hooks while eating brutal elbows, opening up cuts and swelling on Duncan's face -- though Duncan would cause a hematoma to appear on Rebecki's.

The third saw things escalate in intensity, though Duncan seemed to get the edge with his combinations, as well as an anaconda choke attempt. Rebecki didn't back down, however, throwing power shots until the final horn.
