THE day after Daniel Bryan’s retirement, reality set in for the WWE Superstar and his friends and family.

Bryan, who retired at the end of “Monday Night Raw” in Seattle, did an interview on the “Off The Top Rope” segment on ESPN.

Bryan, 34, admitted to having 10 concussions that were able to be diagnosed. There were likely more.

He also discussed an EEG test that returned with scary news about his brain - including slowing and a lesion - and admitted to hiding the fact that he was having post-concussion seizures from others.

“I have had post-concussion seizures that I’ve hid, for a long time,” Bryan told ESPN.

“There was never any evidence to see why I would have these seizures - but then we finally found some.”

Asked what his advice to young athletes in concussion-prone sports would be, Bryan said: “Be cognisant of it.

“One of the mistakes the prior generation has made, including myself because we weren’t aware, was if you get a concussion you need to record it. Because one of the worst things that you can do is get a concussion and then go back to doing a contact sport before your brain is really healed.

“That’s especially true for younger people. There’s this mentality within sports and especially within sports like football, with wrestling, with fighting, with all that kind of stuff - ‘No, I’m going to tough it out, it’s just a ding’. If you’re a competitor, you have that in you to feel that.

“But you have a responsibility to yourself, your family, your friends to report it, just to help yourself.”
