(Getty)Matt Mitrione is coming off a huge win. On Saturday, he won with a 19-second knockout of Philip de Fries. It was a hugely needed win after Mitrione suffered two losses in his last two fights. Now Mitrione is using the spotlight to talk about trans fighter Fallon Fox.

While on the MMA Hour, Mitrione repeatedly called the postoperative transgender female a "he." Mitrione also called Fox, who is scheduled to fight again in May, a sociopath and a freak.

Rose Namajunas spent just 12 seconds fighting at Invicta on Friday. After months of preparation for her bout with Kathina Catron, Namajunas hit a flying armbar and won by submission in just 12 seconds. The fight starts right around the one-minute mark, but it's worth watching the entire, moving video.

See as she prepares to walk out with the help of her boyfriend, UFC heavyweight Pat Barry. See the entire fight, because it is just 12 seconds long. See how she breaks down in tears as her arm is being raised and the emotion of her accomplishment hit her. See Barry show some athleticism, too, as he flies onto the side of the cage to congratulate his girl.

Fighting at straw weight (115 lbs.), Namajunas won four amateur fights before winning her first pro bout in January. She is now 2-0, and clearly is an exciting fighter to keep an eye on.

Perhaps the last-minute opponent change was exactly what Gegard Mousasi needed. The former Strikeforce light heavyweight champion made his debut on Saturday and pulled out a decision over Ilir Latifi, a late replacement after Alexander Gustafsson was not cleared for the fight because of a cut. Mousasi pulled out the unanimous decision win, but shared afterwards that he was dealing with a knee injury.

"I don't want to talk a lot about my injury, but I can tell that this injury, I'm pretty sure 95 percent wouldn't fight, from other fighters," Mousasi said in the postfight press conference.

"You know, I stepped up, I didn't cancel the show, you know, I don't know, we go from here, you know."

In other action, Ross Pearson notched a second-round TKO over Ryan Couture. Matt Mitrione stopped his losing streak with a 19-second KO of Philip de Fries.

And Uriah Hall can fly, too! (Getty)Leading into UFC on Fuel and Invicta, it's been a drama-filled week of MMA. What was hot and what wasn't?

Hot — Pat Curran: Bellator's featherweight champion held onto his belt on Thursday night with a first-round submission of Shabhulat Shamhalaev. It's been two years since his last loss. Since then, he has six wins, including two title defenses.

Not — Practical jokes: When Alexander Gustafsson's status for Saturday's fight was still uncertain, Wanderlei Silva tweeted that he was in for Gustafsson against Gegard Mousasi. He even told media members privately that he was fighting. But the next day he revealed it was an "April Fool's Day" joke. A joke, or a lie?

Hot — Uriah Hall: When he knocked out Adam Cella in the first round of "The Ultimate Fighter," it was hailed as the nastiest knockout ever on TUF. Then Hall went and topped it. He knocked out Bubba McDaniel in a vicious, nine-second bout that ended with McDaniel asking what happened, and UFC president Dana White wondering if it was right to applaud Hall's performance.

Not — Fight-ruining cuts: What was worse — Gustafsson getting cut a week before his fight with Mousasi, or the will-he-or-won't-he drama leading up the the Swedish MMA Federation's medical committee deciding that he couldn't fight? Or was the worst part that they made that decision days before the weigh-in when they could have given the cut more time to heal? It's a bad deal all around.

Still taking temperature — Ilir Latifi: Gustafsson's training partner has the opportunity of his life as he steps in on Saturday to fight Mousasi in the main event of UFC on Fuel 9. He can make his UFC debut very memorable, but will it be good or bad for him.

Who the heck is Ilir Latifi, anyway? When the Swedish MMA Federation stopped Alexander Gustafsson from fighting because of a cut, the UFC needed a quick replacement for the main event. Latifi, Gustafsson's training partner, stepped up, but we don't know much about him except that he's on a three-fight win streak. Will he take advantage of the opportunity?

Overeem was knocked out in February. (Getty)The Blackzillians, the south Florida training home of Rashad Evans, Alistair Overeem, Anthony Johnson, Matt Mitrione and other top fighters, made a major move to improve their results. They hired Kenny Monday, an Olympic gold medalist in wrestling, boxing coach Pedro Diaz, and Guillermo Rigondeaux, a two-time Olympic gold medalist boxer, joined the team.

Monday won gold in 1988 and silver in 1992 as a freestyle wrestler. He had one MMA fight in 1997, but mostly has focused on working with wrestlers working towards the Olympics. Diaz has worked with Miguel Cotto in the past.

It's not surprising to see the Blackzilians make moves after they have suffered high profile losses. Overeem was knocked out by Antonio Silva at UFC 156 and Evans lost to Antonio Rogerio Nogueira by decision on the same card. Thiago Silva had his November win over Stanislav Nedkov overturned because of a failed drug test. Michael Johnson lost to Myles Jury at UFC 155. Mitrione is riding a a two-fight losing streak into his bout this Saturday with Philip De Fries, though just one of those fights came under the Blackzillians' tutelage.

Melvin Guillard lost his last two fights, and then announced on Twitter that he was leaving the Blackzillians to head back to Greg Jackson's camp. Unfortunately, he wasn't welcomed back to his old team.

Evans is fighting Dan Henderson at UFC 161 in June, and Thiago Silva will fight Rafael Cavalcante at a UFC on Fuel card in June. Both fights will show if the new coaches have made a difference.

(Championship Fighting Alliance)Fallon Fox, the postoperative trans fighter who is looking to continue her MMA career, has been cleared of any wrongdoing in getting a fighter's license in Florida.

The question asked by the Florida commission was whether Fox, who fought in Florida in March, had obtained a license fraudulently. She was given her license in Florida after saying she had a license in California. She was given a receipt for her application in California, and thought that was a license. Now, Florida has cleared her, opening the door for her to apply for another license there.

And it appears she will need one. Allanna Jones has agreed to a match-up with Fox for May 24 bout with Championship Fighting Alliance.

(The Mauler)Alexander Gustafsson's fight with Gegard Mousasi was called off because of a cut on Gustafsson's face. He posted a picture of that cut on his website.

He sustained the cut during wrestling practice last week. Gustaffson said he lost his balance and hit his eyebrow. The cut received three stitches. He was ready to fight until the doctors told him he couldn't compete.

The problem with the cut is not so much its size or depth, but its location. If it was reopened in a fight, it's unlikely the fight would go on because the blood would impair Gustafsson's vision to a point that it would make the fight unfair. A cut like that would open with ease, too.

So now the UFC turns to Ilir Latifi, Gustafsson's training partner, to fight Gegard Mousasi in a main event.
