It's a disclaimer that goes along with every single MMA event: Card is subject to change.
And to be frank, Saturday's UFC Fight Night in Las Vegas was hit hard by change. This card was supposed to feature the return of TJ Dillashaw, a former bantamweight champion who lost his belt to a drug suspension two years ago, in a fight against Cory Sandhagen, the fastest-rising contender in the division.
You lose a fight of that magnitude, the card is going to suffer. There's no way around it. Fortunately, however, Saturday's card (8 p.m. ET on ESPN, prelims at 6 p.m. on ESPN+) has some depth to soften the blow. Here are a few storylines to look out for this weekend:
The new main event is a flyweight (but really strawweight) bout between Marina Rodriguez (13-1-2) and Michelle Waterson (18-8). The two will weigh in at 125 pounds, but this is essentially a 115-pound bout for which neither fighter will cut weight because of the short notice. And it's a big spot for Rodriguez, who is a potential future champ but has shown some growing pains as she has taken on the elite of the strawweight division. At 34, she's "new blood" in terms of the title picture, but she needs to get it done now.
When this card lost its main event, it added a welterweight matchup between Neil Magny (24-8) and Geoff Neal (13-3). Neal is coming off a loss to Stephen Thompson in his first UFC main event in December. Had he won, his stock would have been on fire. That was a tough stylistic matchup for Neal, but his potential is still through the roof. He'll have to be at his best to beat Magny, a highly ranked veteran who could fight Khamzat Chimaev next with a win.
Donald Cerrone (36-15, 2 NC), 38, will make his 37th walk to the Octagon, tying fellow lightweight Jim Miller. This fight was supposed to be against former teammate Diego Sanchez but is now against Alex Morono (18-7, 1 NC). There was a time when it felt we'd never see the end of Cerrone's career, but for the first time, it seems possible 2021 could be the final year for Cerrone. Even if it's not, we're in the twilight of Cerrone's historic career, so this is worth tuning in for.
Veteran lightweight Diego Ferreira (17-3) had his chance in February to win a big fight and nab a ranked opponent next, but he came up short against Beneil Dariush. That was a must-win for Ferreira. Just look at what happened to Dariush and him afterward. Ferreira is now fighting a guy most lightweights want to avoid in Gregor Gillespie (13-1), and Dariush is in a high-profile bout against Tony Ferguson next week on pay-per-view. That's a tough one to swallow, but Ferreira is a veteran and he needs a good showing here. As does Gillespie, who has shown a ton of potential but is coming off the first loss of his career and hasn't won in over two years.
By the numbers
4: UFC main event appearances by Waterson (including Saturday), which will tie her with flyweight champion Valentina Shevchenko for fourth most among women. Former bantamweight champs Ronda Rousey and Holly Holm each have headlined six cards, one more than two-division titlist Amanda Nunes.
7-0: Rodriguez's record in fights that end in a finish (six by knockout, one by submission).
0: Finishes by Waterson since December 2016. She has fought eight times since then, winning four of those bouts, all by decision, including two split decisions. Before that, Waterson had had finishes in 12 of her 14 wins.
2: Draws in the UFC for Rodriguez, making her the only woman with multiple draws and one of only five modern-era fighters overall to have more than a single draw in the UFC.
14: Takedowns in the UFC by Waterson, the seventh most in strawweight history, leading to her nine submission victories. The goal for Rodriguez, then, is to keep the fight standing. In her three UFC wins, Rodriguez has defended the takedown 89% of the time (8 of 9). In her three draws/losses, she has defended takedowns just 45% of the time (8 of 18).

And the winner is ...
"On the feet, I feel Rodriguez definitely has a boxing advantage," said Carla Esparza, a former UFC strawweight champion who has fought -- and defeated -- both women. "Waterson did land a few kicks on me, and my leg was black and blue, but Rodriguez has a reach and power advantage. As far as the wrestling, I could see Waterson taking it to the ground. She has nice throws that I've seen her hit. It's just a matter of closing that gap, which is difficult because she likes to be at range with her kicks. But if she's able to create that clash of bodies, I could see her taking Rodriguez off her feet."

Four more things to know (from ESPN Stats & Information)
1. In the co-main event, Donald "Cowboy" Cerrone steps back into the Octagon in hopes of snapping a five-fight winless streak (0-4, 1 NC) when he takes on Alex Morono. Cerrone, the UFC's career wins leader, will once again tie Jim Miller for most fights in UFC history. Cerrone will also try to break a tie with Charles Oliveira for the most UFC finishes. This will be the 21st time that Cerrone will be in a UFC main or co-main event, breaking a tie with UFC Hall of Famer Randy Couture and Vitor Belfort for third most in UFC history, behind Anderson Silva (24) and Michael Bisping (22).
2. Cerrone isn't the only fighter on the card with massive UFC experience. Saturday will mark the 25th time Neil Magny steps into the Octagon when he takes on Geoff Neal on the main card. Magny will break a tie with Josh Koscheck for the third-most fights in the welterweight division, and he will be trying for his 18th win in the division, which would put him one behind UFC Hall of Famer Georges St-Pierre for the most of all time.
3. Lightweights Diego Ferreira and Gregor Gillespie meet with both coming off a loss -- but in much different circumstances. Ferreira fell to Beneil Dariush in a split decision just three months ago. Gillespie last fought in November 2019 and suffered his first defeat, a brutal head-kick knockout loss to Kevin Lee.
5. When Carlston Harris steps into the Octagon to face Christian Aguilera during the prelims, he will be the first person to represent Guyana in the UFC. In all, the prelims will have seven countries represented: the United States, Brazil, South Korea, Cameroon, Uzbekistan, Slovakia and Guyana.
