It appeared CM Punk's UFC debut vs. newcomer Mickey Gall was set for UFC 202 in late August but according to MMA journalist Ariel Helwani, the fight will not be taking place during WWE's SummerSlam weekend.
Helwani tweeted that the fight date is far from a done deal but it's looking like it will happen at UFC 203 on September 10th in Cleveland. Helwani wrote the following on Punk, who signed with UFC in December 2014:
Current plan at the moment is CM Punk vs. Mickey Gall at UFC 203, per sources. Far from a done deal but that's the direction as of this AM.— Ariel Helwani (@arielhelwani) June 21, 2016
