The UFC’s return to Texas this weekend has one more bout that has made its way to official status.

Oskar Piechota (10-0 MMA, 1-0 UFC) will take on promotional newcomer Tim Williams (15-3 MMA, 0-0 UFC) in a middleweight fight. Promotion officials formalized the booking today.

UFC Fight Night 126 takes place Sunday at Frank Erwin Center in Austin, Texas. It airs on FS1 following early prelims on UFC Fight Pass. Although the lineup is mostly set, a women’s strawweight fight featuring Jessica Aguilar in still in limbo while she waits for a replacement for the injured Livia Renata Souza.

Piechota made his promotional debut this past October in Poland at UFC Fight Night 118. There, in front of his home crowd, he stayed unbeaten with a unanimous decision win over Jonathan Wilson. The only blemish on Piechota’s resume is a 2013 split draw.

Williams’ lengthy career has been on the East Coast, where he has a dozen fights under the CFFC banner. He comes to the UFC on a five-fight winning streak, including victories over UFC veterans Jay Silva and Nah-Shon Burrell.
