Latest UFC rankings update: Valentina Shevchenko rises, Holly Holm falls following UFC on FOX 20 in Chicago

Ultimate Fighting Championship (UFC) recently tied a ribbon around its UFC on FOX 20 mixed martial arts (MMA) event, which took place last Sat. night (July 23, 2016) inside United Center in Chicago, Illinois (results), and there was a lot to talk about when all was said and done.

You can thank Valentina Shevchenko and Edson Barboza for that.

"Bullet" continued her march through the bantamweight division by turning away former champion Holly Holm in the five-round main event (see it). Barboza, meanwhile, put the rest of the 155-pound division on notice by knocking around ex-Strikeforce champ Gilbert Melendez (replay), who debuts at No. 14 after his extended layoff.

Chad Mendes, meanwhile, was pulled from the featherweight list following his USADA suspension (details).

That's not all.
