Holly Holm -- I Want a Rematch

Holly Holm says her loss to Miesha Tate is "not the end for me" -- and has challenged the new champ to a rematch.

Holly went to Instagram and posted a pic of herself in the chokehold that did her in ... saying, "This is how Saturday night ended but it's not the end for me."

"I am going to train hard and show that I am better than this. I am down but not out. Thank you @mieshatate for the opportunity last weekend. Well done. What do you say? ....Let's do this again."

She added the hashtag #downbutnotout.
