UFC.com announced late this evening that TUF 12 contestant Cody McKenzie has unfortunately had to pull out of his fight with Bart Palaszewski (35-14) at UFC 130 in Las Vegas. UFC veteran Gleison Tibau (22-7) has verbally agreed to step in on roughly three weeks notice against Palaszewski on the card. 

Tibau most recently defeated Kurt Pellegrino by split decision at UFC 128 in March, to bring his UFC record to 8-5. Palaszewski is now faced with the task of adjusting to an opponent with a completely different style on short notice in his debut fight in the UFC. The longtime IFL and WEC veteran is coming off a close split-decision loss to Kamal Shalorus at the final WEC card back in December. Before that setback, he had won four in a row and was a contender for the WEC lightweight title. He will look to return to form against the massive Tibau on May 28th.
