Ronda Rousey -- 'Depressed' and 'Bummed' ... There Will Be a Rematch!

Ronda Rousey is "depressed" and "bummed out" after losing her UFC title to Holly Holm, but UFC Prez Dana White tells TMZ Sports there will absolutely be a rematch.

We're told Ronda was kept overnight in an Australian hospital. White tells us she does not have a concussion but there's a "very big gash" in the middle of her lip. White and team searched for the best plastic surgeon in Australia, who's going to do his handiwork today.

Ronda, who spent the night in the hospital with her sister, did not talk about the loss. As Dana tells us, "The last thing a fighter wants to do is talk about a fight when they lose." White says, "There was not a lot of talking."

As for the fight, Dana says it broke all records. He was especially psyched that it "destroyed" the previous record for bars showing a UFC fight -- a record previously set by the Lesnar/Velasquez heavyweight title fight. A record number of bars in various countries showed the fight, including the U.S., Australia, New Zealand and Canada.

Dana had high praise for both fighters. As for Ronda, he says, "What this woman has done has never been done before. We've been doing this for 15 years with huge stars, and Ronda has broken every record."

As for Holly, White says people didn't give her due credit going in ... "Holly had 45 fights before and multiple world titles. She was totally calm and cool." And he says she's score a phenomenal payday.

Dana says, "There will absolutely be a rematch. It's the fight that makes sense."
