Today is not a good day for combat sports.

Former UFC light heavyweight champion Rashad Evans will no longer be making his middleweight debut at the upcoming UFC 206 pay-per-view (PPV) event, scheduled for Dec. 10, 2016 inside Air Canada Centre in Toronto, Ontario, Canada.

That’s according to his former opponent, Tim Kennedy, who dropped a bomb during The MMA Hour when suggesting that “Suga” may be finished as a mixed martial arts (MMA) fighter, as a result of possible brain damage.

His words:

"They're not (letting him fight). I'm not fighting Rashad. I found out yesterday. I think it's brain damage. Welcome to the sport where we punch each other in the head. When you have to back-to-back athletic commissions not issuing you a license, I don't know what that means for Rashad. It's a slippery slope moving forward for him."

And while Evans was deemed medically unfit to compete by Office of the Athletics Commission in Ontario — less than a month after New York State Athletic Commission refused to grant him a license to fight — his manager isn’t ready to wave the white flag just yet.

"He's fine, guys," Ali Abdel-Aziz told MMA Fighting. "Rashad is fine. There's nothing wrong with him."

“Suga” told us right here at MMAmania.com that he's never felt better and that his most recent training camp was “amazing” (read it).

Evans (19-5-1) hasn’t seen the win column in over three years, coming off back-to-back losses to light heavyweight bruisers Ryan Bader and Glover Teixeira. The Ultimate Fighter (TUF) 2 champion has been competing in MMA for over a decade and has certainly seen his fair share of wear and tear.

No word yet on if or when Kennedy will receive a new opponent.
