The boxing match between Mike Tyson and Jake Paul originally scheduled to stream live on Netflix July 20 has been postponed, according to a tweet from Most Valuable Promotions, which is co-producing the fight. The stated reason for the delay is an ulcer flare-up that Tyson is suffering from. Most Valuable Promotions, owned by Jake Paul and Nakisa Bidarian, announced the delay in a statement by noting that medical professionals had advised Tyson to only do light training over the next few weeks before the boxing legend could return to full training.

“Both Mike and Jake are in agreement that it is only fair to ensure that both athletes have equal training time to prepare for this important match and are able to compete at the highest level,” Most Valuable Promotions . “The health and well-being of athletes is our top priority, and we fully support Mike in taking the necessary time to allow him to perform at the level he expects.” Previously purchased tickets to the match will be honored for the yet unannounced date of the fight at AT&T Stadium in Arlington, Texas.

Tyson released a statement thanking his fans around the world for their support, explaining that his doctor had advised him he should take it easy. But Tyson also stressed that he was in good shape and didn’t hesitate to talk some trash about Paul. “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,” Tyson said in a statement tweeted .
