Mike Tyson vs. Jake Paul is postponed.

The heavily-anticipated fight will not take place on July 20 as expected after Tyson suffered an ulcer flare up this week.

“I want to thank my fans around the world for their support and understanding during this time. Unfortunately, due to my ulcer flareup, I have been advised by my doctor to lighten my training for a few weeks to rest and recover,” Mike Tyson said in a statement. “My body is in better overall shape than it has been since the 1990s and I will be back to my full training schedule soon.

“Jake Paul, this may have bought you some time, but in the end you will still be knocked out and out of boxing for good. I appreciate everyone’s patience and can’t wait to deliver an unforgettable performance later this year.”
