The Ultimate Fighting Championship returns to Brazil this weekend for the first time in 2020, and the headliner is in jeopardy.
UFC Fight Night 170 is headlined by an intriguing lightweight clash between Kevin Lee and Charles Oliveira, but that is now in doubt as Lee initially missed the weigh-in window, but stepped on the scale in time. After a brief stint at welterweight, Lee (18-5) rebounded spectacularly in his return to lightweight. "The Motown Phenom" knocked out Gregor Gillespie with a head kick in less than three minutes at UFC 244.
