A video has surfaced online of Roman Reigns laying in a hospital bed explaining how he went from preparing to face Seth Rollins at tonight's Night of Champions pay-per-view event in Nashville, Tennessee, to calling 911 for help and having emergency surgery to repair an incarcerated hernia.

"Yesterday I was here in Nashville promoting Night of Champions and my match against Seth Rollins," said Reigns. "I was laying in bed and all of a sudden I felt a really sharp pain right below my belly button in my bladder region. Tried to gut it out but it just kept getting worse so I ended up calling 911. They sent an ambulance and once I got to the hospital, the doctor said I had a hernia and I needed to go into emergency surgery and here I am now."

Reigns could be released from the hospital today. WWE physician Dr. Amann noted to WWE.com that recovery time will be 4-6 weeks, but "this was a pretty significant hernia, so it will probably be closer to six weeks."

As noted earlier, Reigns also sent out this message on Twitter today.

Thank you everyone for your kind words, support and prayers!! I'm hurting right now but it's great to know good people have my back!!  Roman Reigns (@WWERomanReigns) September 21, 2014



WWE did not announce a replacement match for Reigns's scheduled match against Rollins at Night of Champions tonight.
