LAS VEGAS — Professional women’s boxing champion Heather Hardy will resume her MMA career on Oct. 20 when she takes on Kristina Williams at Bellator 185 at Mohegan Sun, The Post has learned.

Hardy, 20-0-1 as a professional boxer, made her MMA debut last June when she earned a bloody third-round TKO over Alice Yauger at BellatorNYC at Madison Square Garden. Hardy isn’t abandoning her boxing career and hopes to return to the ring in December.

She currently trains for both sports.

“I can’t wait for it,” Hardy told The Post of her next MMA fight. “I made huge improvements in my boxing after every fight and I’m seeing the same thing in MMA. I’m looking forward to getting back in there again.”

Bellator CEO Scott Coker is glad to add Hardy to the Mohegan card.

“Heather is an incredibly talented young woman with an already impressive boxing career that has seen her win multiple world titles,” Coker said. “I believe she has a very bright future in MMA and we’re thrilled that we were able to work with her and [promoter] Lou DiBella to make this opportunity happen. We are looking forward to her next fight at Mohegan Sun, just a short drive from her hometown in Brooklyn.”
