Lingering symptoms of Covid-19 almost stopped Khamzat Chimaev from fighting, but doctors worried the UFC star actually had cancer.
Chimaev, who fights Gilbert Burns at UFC 273 tonight, made an instant impression after debuting in the UFC in 2020. He set records for the fastest wins and fastest three-fight winning streak in promotional history and announced himself as a top prospect.
The 27-year-old was set for a big step up in competition at the end of that year, being booked to fight top-ranked welterweight Leon Edwards. Chimaev pulled out of the fight three times due to Covid-19 issues and that was just the start of the Chechen's problems.
