"They were going to have me fight Maynard on that card. I said yes to that deal right away. I guess it turns out that it’s not going to happen. I’m back to fighting Guida," Pettis told HeavyMMA.com. "It sucks that he got injured, because it kinda puts the whole lightweight division back on standstill."
"For three or four days I thought I was going to fight on May 28 and now it’s just killing me, so I’m going to take it out on Clay Guida."
