Despite handing out fight posters with Gilbert Melendez and Khabib Nurmagomedov included for UFC 170, UFC president Dana White isn’t ready to announce the bout.

After it was revealed as official over the weekend, White took to Twitter to say “not so fast.”

“Not true,” White wrote, in response to a post made by the UFC Tonight Twitter page, “this fight is not done yet.”

Targeted for February 22 from Las Vegas, the card currently features a main event between UFC female bantamweight champion Ronda Rousey and Sara McMann. Also, Daniel Cormier will face Rashad Evans.
