Cris Cyborg says she's not sweating Holly Holm's famous leg-striking power -- it's Holly who should be worried about Cyborg's fists.

Cyborg vs. Holm is the main event at UFC 219 on Dec. 30 in Vegas -- and Cris says she's trying to rally her fans to help out the kids at the local hospitals while she's in town.
