Most fans are awaiting tonight’s (Sat., January 20, 2018) UFC 220 from TD Garden in Boston, Massachusetts, for its massive Stipe Miocic vs. Francis Ngannou heavyweight title main event, but a stoppage that would make both hulking knockout artists proud kicked off the event.

Touted rising star Islam Makhachev met longtime Brazilian veteran Gleison Tibau, who had been out of action since December 4, 2015, after being suspended for two years by USADA. It may have been that cage rust coupled with Makhachev’s no-longer-hidden talent, but no matter what the reason, the 15-1 Dagestani scored his biggest UFC win in jaw-dropping fashion to get UFC 220 started off right.
