UFC pulls middleweight from the card following a fall down the stars at a UFC facility

UFC middleweight Deron Winn suffered an unfortunate accident at UFC performance institute.

UFC PI has become a hub for UFC athletes with many of them training alongside each other despite ongoing feuds.

Deron Winn was at the institute hoping to prepare for his matchup against Julian Marquez. Marquez is a member of the James krause camp and has his own plate full.

Winn was in the middle of a weight cut when he fainted and fell down a flight of stairs on Wednesday.

During the fall he reported suffered a mild concussion that rendered him unable to compete this weekend.

“Hey all- yesterday at the UFC PI, I fainted and had a freak accident,” Winn shared on Twitter. “I fell down the stairs, hit my head and neck pretty hard. Sustained a mild concussion.”

“They rushed me to the hospital and ran a bunch of tests on me,” Winn continued. “The majority of the tests came back normal, so I’m thankful for that. Since I suffered the concussion the UFC and medical staff has decided to pull me from my fight this weekend. I am devastated. I have put so much work in these last couple months. I hope to rebook soon. Sorry to my opponent, and sorry to all (who) have invested into me this camp. I’m heartbroken. Love all.”

Winn is a longtime friend and teammate of Daniel Cormier’s. Cormier got into hot water during a Winn bout last year when Phil Hawes threatened Cormier in cage over bias.

Hawes went so far as to challenge Cormier to a fight. He told the commentator, “I’ll cool off and next week you can fight me.”

Cormier urged him to be respectful.

Referee Herb Dean got in between the two smelling trouble.

Cormier was reluctant to back off and offered a meek explanation that he’s not the match maker – which everyone knows.

Hawes didn’t dwell on the exchange afterwards and had the following to say during the press conference:

“It’s just a misunderstanding on my behalf, you know, ’cause ‘DC’ is such a role model to me. You know what I mean? Two-weight world champion and just a freaking stellar dude. So there was a little miscommunication, wrong place, wrong time. I apologize, ‘DC’. Don’t beat me up.”
