Gaethje, nor the UFC have responded to Hooker's injury. It's unclear if Gaethje will remain on the card if Hooker is removed. The lightweight fight was the main support for UFC 313, headlined by UFC light heavyweight champion Alex Pereira vs. Magomed Ankalaev on March 8.

The UFC 313 co-main event is in need of saving. Justin Gaethje vs. Dan Hooker, one of the hottest fights of the year, is no longer taking place next weekend in Las Vegas after a broken hand forced Hooker off the card.

Fiziev was one of the first lightweights to offer his services as a replacement, along with Renato Moicano and Mateusz Gamrot, and the Azerbaijani got the nod. He will fight Gaethje two years after losing a narrow decision to the American in London.
