The former flyweight champion, who now competes in the 145-pound weight class, broke the news in a video posted to his YouTube channel.
"Unfortunately, I have to break the news that I will not be competing at UFC 307. I suffered a non-surgical injury during sparring, but the UFC medical staff informed me that I would not be able to recover for the tournament.
I tried to recover as best as I could with the [UFC Performance Institute] team here, and unfortunately it's out of my hands now. I apologize to Movsar and his team. I was looking forward to punching this guy in the face."
