“Chimaev has fought at welterweight throughout his career. This time he couldn't make weight, but that doesn't mean it will be like this all the time. Of course, it was difficult for him to gain weight for this weight class, but he did it. The bottom line is that we've made it easy and we'll be fighting in the middleweight division for some fights, but we'll also continue to compete in the welterweight division."
Recall that on the eve of UFC 279, Chimaev could not invest in the welterweight limit, so his fight with Nate Diaz was canceled. As a result, the Borz fought Kevin Holland in a catchweight division, defeating him by choke in the first round.
