WWE star Roman Reigns was forced to miss Sunday’s Night of Champions match and undergo emergency surgery.

Roman Reigns Emergency Surgery

Instead of fighting Seth Rollins in the ring, Reigns was recovering from emergency surgery to repair an incarcerated hernia. The wrestler called 911 Saturday after experiencing a persistent, sharp pain, he told the WWE Network. After he was hospitalized, doctors told Reigns that he had to have surgery immediately.

Prior to his hospitalization, Reigns had been competing with a hernia, according to physician Dr. Chris Amann. However, the injury had gotten increasingly worse, to the point where he had no choice but to have surgery if he wanted to get back into the ring.

“This wasn’t related to a specific injury that occurred in the ring. Roman has had a pre-existing hernia for some time, which unfortunately had become acutely painful, which led to him going to the emergency room in Nashville,” Amann told WWE.com. “He was found to have a large hernia that was unable to be reduced, which means pushed back into the abdominal cavity. As a result, it was necessary to perform an emergency operation to open up the hernia sac and try and push it back into the abdominal cavity.”

Reigns’ recovery time could be anywhere from four to six weeks. Amann is of the belief that due to the severity of Reigns’ particular injury, his recovery time will be on the longer end of the spectrum, which means he could potentially miss October’s pay-per-view Hell in a Cell fight.
