Following last week's UFC 250 which was headlined by Amanda Nunes and Felicia Spencer, the UFC brought to us another high-octane card headlined by women. UFC Fight Night 172, the second of UFC's closed doors events in Las Vegas was held inside the promotion's Apex facility on Saturday night.Although people expected this card to be a bit of a dampener compared to last week's UFC 250 or the upcoming UFC 251 due to the lack of popular names, the fights were entertaining and the card an engaging one, full of breakneck finishes as well as nail-biting thrillers.The scheduled main event saw Cynthia Calvillo make her flyweight debut against former title contender Jessica Eye. Calvillo claimed a lopsided unanimous decision win against Eye and emerged as the new contender for reigning UFC flyweight champion Valentina Shevchenko's title.The co-main event from the night saw a grudge match between middleweights Karl Roberson and Marvin Vettori. Vettori claimed the bragging rights as he destroyed Roberson in the first round, forcing the latter to submit to a nasty rear-naked choke.Decisions were tough tonight! 💰 #UFCVegas2 pic.twitter.com/g3DSxQTI9Z— UFC (@ufc) June 14, 2020Without further ado, let's glance through the highlights of UFC Fight Night 172.Preliminary cardThe UFC Fight Night 172 card prelims had a few noteworthy contests and perfectly set the stage for the main card to follow.
