Saturday's UFC 303 event in Las Vegas was chaotic, but absolutely entertaining.

The card was originally expected to headlined by a welterweight fight between Conor McGregor and Michael Chandler.

When the Irishman suffered an injury, causing the fight to be canceled, the UFC booked a new main event on just two weeks' notice: A light heavyweight title rematch between champion Alex Pereira and challenger Jiri Prochazka. Thankfully, that fight held together, with the Brazilian defending the belt with a second-round head kick KO.

The co-main event also came together on two weeks' notice, with Brian Ortega booked to meet Diego Lopes in a clash of featherweight contenders.

When Ortega fell ill just hours ahead of the contest, though, the UFC called upon Dan Ige to step in. He performed well for somebody who woke up that morning without fight plans, but ultimately lost a decision to Lopes.

Earlier on the card, we got another short-notice fight, with former light heavyweight title challenger Anthony Smith taking on middleweight contender Roman Dolidze in a 205-pound clash. The fight was the result of a string of cancellations and issues involving Khalil Rountree, Jamahal Hill and Carlos Ulberg, and it went Dolidze's way by decision in the end.

The Smith vs. Dolidze fight was preceded by a women's bantamweight clash between Mayra Bueno Silva and Macy Chiasson, which ended when the former received a deep cut on the brow, plus a welterweight scrap between top-15 contenders Michael Page and Ian Machado Garry, which Garry won by decision.

Keep scrolling for the fights we want to see for card's biggest winners when the dust has settled.

Alex Pereira vs. Magomed Ankalaev

Alex Pereira now holds two second-round stoppage wins over Jiri Prochazka, which effectively proves he is the superior fighter in their rivalry and signals it's time for him to move onto other challengers.

In the immediate aftermath of the South American's win, UFC commentator Joe Rogan expressed interest in seeing the light heavyweight champion move up to heavyweight in search of a third MMA title.

Rogan has clearly forgotten about the existence of Magomed Ankalaev.

The Russian is unbeaten in his last 12 fights, and he has triumphed over some of the top light heavyweights in the UFC in that time. Currently ranked No. 2 in the division, he arguably deserved a title shot before Prochazka got his second shot at UFC 303, but he wasn't available at such short notice.

Now is the time, though. The 32-year-old is deserving, and as a suffocating wrestler with big power in his hands, he's the kind of stylistic challenge Pereira has yet to face.

Book it for an upcoming pay-per-view, and if the champion retains his title, then we can talk seriously about him moving up to heavyweight.

Diego Lopes vs. Brian Ortega

Rising featherweight contender Diego Lopes had to work surprisingly hard against last-minute replacement opponent Dan Ige, but he got the decision win all the same.

After the win, the Brazilian deserves a big step up in competition. That's not just because he's now won four straight at featherweight, but also because he saved the UFC's hide by agreeing to fight Ortega on two weeks' notice, then agreeing to fight Ortega at lightweight, then agreeing to fight Ige at 165 pounds with just a few hours' notice when Ortega got sick.

As a new face in the featherweight top 15, there are plenty of fresh matchups for him, but the best option seems like a rescheduled clash with Ortega.

The American, who has not fought since he choked out Yair Rodriguez earlier this year, is ranked No. 3 at featherweight. While he didn't endear himself with the UFC by pulling out of his fight with Lopes at the eleventh hour, he's still the kind of test Lopes will need to pass before becoming a legitimate title contender.

It's also an excellent fight on paper, as both men have world-class grappling and excellent striking to fall back on.

Roman Dolidze vs. Caio Borralho

Roman Dolidze impressed by beating Anthony Smith in their short-notice UFC 303 light heavyweight fight, but the unanimous decision win probably won't do much to raise his stock at middleweight, as he is still riding back-to-back losses in the division.

Our pick for his next fight back at 185 pounds is Caio Borralho.

The Brazilian, 31, is riding eight straight wins, and his latest—a brutal knockout of Paul Craig—pushed him into the rankings.

Now sitting at No. 12, he's ready for another step up, and the 10th-ranked Dolidze seems like a great choice. It's an interesting style clash on paper, and it would tell us a lot about where both men belong in the division.

Of course, if Dolidze gets his way, his next fight will be against Khamzat Chimaev, who he called out post fight. That's a great matchup for both, but the problem is that it's still not clear when the Russian will be healthy enough to fight again.

The 30-year-old was only just forced out of a fight with Robert Whittaker due to what seems to be a recurring illness, and his future remains uncertain.

Macy Chiasson vs. Ketlen Vieira

Macy Chiasson picked up the biggest win of her career on the UFC 303 main card, slicing former title challenger Mayra Bueno Silva open with an elbow to force a doctor stoppage.

Bueno Silva took issue with the stoppage, but the wound on her brow was brutal, so her protesting had little merit.

The win should send Chiasson crashing into the top five of the women's bantamweight division. Under different circumstances, she might be looking at a title shot from here, but we know the next crack at champion Raquel Pennington will most likely go to former champ Julianna Pena, and Kayla Harrison is almost certainly next in line beyond that.

Based on all that, the best option for Chiasson's next fight seems to be Ketlen Vieira.

The Brazilian is riding a win over Pannie Kianzad and is currently ranked No. 2 in the bantamweight division. Much like Chiasson, she's right on the cusp of a title shot, but she will most likely have to wait for other women to get the chance first.

It only makes sense to pair them together in the meantime, and they actually have some unfinished business, having been matched up to no avail once before.

Ian Machado Garry vs. Colby Covington

Ian Machado Garry's decision win over Michael Page was razor close—so close that many viewers actually scored the fight the other way around.

Nonetheless, the victory pushed the Irishman to a fantastic 15-0 overall and reaffirmed him as one of the top contenders at welterweight.

A title shot isn't far off for the 26-year-old at this point, but he'll probably need another win or two to make it happen.

In terms of his next opponent, he's got options. Jack Della Maddalena is a great choice, as is Shavkat Rakhmonov, whom he called out post-fight. However, our top choice remains a fight with three-time title challenger Colby Covington.

Garry and Covington spent much of this year and last year trading trash talk that seemed to be setting up a high-profile grudge match between them. However, Covington ultimately lost interest in the matchup, claiming Garry is too much of a "nobody."

Covington might want to look in the mirror. His only win in the last three years was against a shop-worn Jorge Masvidal, and he was embarrassed by Leon Edwards in his last fight.

The fact is, at this point, the 36-year-old would be lucky to get a fight with a red-hot contender like Garry. In fact, he should be jumping at the opportunity. If he is able to derail the Irishman's momentum—which seems possible given his wrestling skill—he'll be right back in title contention.

Garry, meanwhile, stands to rocket right into title contention himself by beating an established name like Covington.

It makes all the sense in the world for both guys, and the buildup would be interesting, as they're both known for their unabashed trash talk.
