Watt shocked the NFL world Sunday when just hours before the Carolina game he shared that he dealt with atrial fibrillation earlier in the week. The condition occurs when someone’s heart beats rapidly and irregularly, which eventually could cause a stroke or clot.

In his shocking tweet, he said he decided to share the news because he was informed someone close to him leaked the information and an unnamed publication was going to publish an article on the topic.

“I was assured multiple times from multiple people that there’s nothing else you can do,” Watt said on his heart condition. “You go back and play like normal, it could happen again the next day, it could happen never again in 20 years.”
