Chimaev, with an undefeated record of 14-0, is on a quest for his first UFC title.

Dricus Du Plessis and Khamzat Chimaev completed their final UFC 319 pre-fight business on Friday with a tense faceoff at ceremonial weigh-ins.

If successful against Chimaev, Du Plessis will tie Chris Weidman with three title defenses, which is third in the division's history behind Israel Adesanya and Anderson Silva.
