JASON Kelce had admitted that he thinks he has CTE after criticism over his Secretariat claims.

The decorated former center, 36, accused the 1973 Triple Crown winner of doping on the New Heights podcast he founded with brother Travis.

“Secretariat was juiced to the gills,” Kelce claimed.

“Secretariat just so happens to be right in the heart of the steroid era.

“[In] 1973, every NFL player, every baseball player, they were juicing them to the gills.

“You don’t think Secretariat was f***ing juiced to the rafters? Of course it’s the fastest horse of all-time.”

His comments sparked a backlash on social media, with one user claiming he may have CTE – the brain disease that his been diagnosed in post-mortems of several former NFL players.

“[Y]ou know who else makes unsubstantiated claims not backed up by facts. People suffering from CTE. I’ll admit I don’t know whether @JasonKelce suffers from CTE or not, it’s impossible to know,” they posted.

“I mean I can virtually guarantee that I have CTE, all the research would suggest I have some degree of it,’ Kelce replied.

“I think it is entirely reasonable to assume I have some degree of that pathology.”

The original poster insisted he did not mean to offend Kelce.

“I understand, I don’t take offense at all. what I’m saying is that it’s completely reasonable to think I have CTE,” the podcaster added.

“Even though there is no test to see if I currently have CTE, The evidence suggests I probably do.

“Just like the reality that a lot, if not most of the high level horses of the 70s and 80s were doping because adequate tests were not available.

“But it really doesn’t accomplish anything to bring this up, I don’t know why I started, Secretariat was still a fantastic horse and legendary specimen.”

Retired NFL wideout Antonio Brown, who has become an outspoken social media presence, had a typically controversial response.

He posted: “First step is admitting it. #CTESPN.”

The hashtag relates to a social media page he has created to poke fun at ESPN.

Kelce voiced his concerns about CTE in his Amazon Prime documentary last year.

“There have been little things that are not big things yet but are going to turn into big things the longer I play,” he said.

“Not to dress like an elephant in the NFL room, but I am fearful about what the impacts of playing football are going to mean long-term.

“I have two girls and … some people end up getting CTE and some guys live long, healthy lives.

“I have no idea what’s going to happen with that because I’ve thought about this,’ he said, thinking of the amount of physical impacts in the game and if ‘it might come back to bite me.”
