Holly Hom and Valentina Shevchenko are set to do battle when they go head-to-head at the United Center in Chicago on "UFC on Fox" 20 on Saturday.

Holm is a former UFC women's bantamweight champion and she's the one who handed Ronda Rousey her first loss. "Rowdy" remains sidelined, while Holm went on to lose her belt to Miesha Tate, who in turn fell to Amanda Nunes at UFC 200 earlier this month.

Shevchenko survived a harrowing ordeal in which she was at a chicken restaurant that ended up getting robbed, leading to a shootout involving her trainer. Now that she's survived the ordeal, she's ready to compete at this event.

"It's a situation like you never know when it's [gonna] happen and it was like, why is this happening to me?" Shevchenko told TMZ Sports last month. "It cannot be like this right now, but when it happened it was just a [few] seconds and it was just action. When I saw that the robbers were close to us, it was really scary because it's only one thing, they can [shoot] ... so it was you go or they go, so I'm very happy that it's over."

Holm is 10-1 in the MMA and owns a 3-1 UFC record, while her opponent is 12-2 in the MMA realm and 1-1 in UFC.

The women's fight will co-headling the event with a battle featuring Gilbert Melendez (22-5 MMA, 1-3 UFC) against Edson Barboza (17-4 MMA, 11-4 UFC).

All in all, 12 fights highlight this card.
