The two most recent UFC middleweight title challenges are set to clash in an October headliner.

After falling short to Israel Adesanya in their previous outings, Paulo Costa and Marvin Vettori have agreed to serve as a main event for UFC Fight Night on Oct. 23. The event does not have an announced venue or location.

MMA Junkie verified with a person close to the situation that Costa (13-1 MMA, 5-1 UFC) and Vettori (17-5-1 MMA, 7-3-1 UFC) have agreed to the contest following an initial report from broadcast partner ESPN. The person requested anonymity because the UFC has yet to make an official announcement.

Costa, 30, has not competed since an unsuccessful title challenge in October. At UFC 253, Costa was finished via strikes by Adesanya in Round 2. The finish, and subsequent mocking celebration by Adesanya, seemed to rub Costa the wrong way. Shortly after the fight, Costa vowed to storm back and defeat Adesanya.

It’ll be more than a year between fights for him, though, which included a spat with the UFC brass over claims he never agreed to a reported fight with Jared Cannonier.

Vettori, 27, meanwhile, fell short against Adesanya at UFC 263 in June. The loss ended a five-fight unbeaten streak for the Italian fighter.

The latest UFC Fight Night on Oct. 23 card includes:

• Paulo Costa vs. Marvin Vettori
• Walt Harris vs. Tai Tuivasa
• Randa Markos vs. Livinha Souza
• Daniel Lacerda vs. Jeff Molina
• Jessica-Rose Clark vs. Joselyne Edwards

Since the early days when the sport was anything but a mainstream endeavor, the MMA industry has thrived and survived through various websites, forums, and – perhaps most importantly – social-media platforms.

Fighters interact with fans, each other and many more through the likes of Twitter, Facebook and Instagram, which helps outsiders get a deeper look into the minds of the athletes.

Following Saturday’s UFC on ESPN 28 in Las Vegas, several of the winning and losing fighters, along with their coaches, training partners or family members, took to social media to react to the event or share a message with supporters.

Check out some of those reactions.

The defeated

If Bellator does, indeed, return to Dublin, there’s no way Irish bantamweight Brian Moore is going to miss out.

Moore (14-7 MMA, 5-3 BMMA), who defeated Jordan Winski via unanimous decision at Bellator 263 on Saturday, wants to ensure that he’s part of the rumored Nov. 5 Bellator card in Ireland.

The 33-year-old hasn’t competed at home since losing to current featherweight champion A.J. McKee in November 2017 and was forced to miss out on the promotion’s past three Dublin cards.

“November, Dublin,” Moore said at the post-fight news conference. “I’m not missing that show. I headlined that show against A.J. McKee in a very entertaining, very close fight, and I haven’t been able to compete in that since with different injuries. Now I’m on a three-fight win streak, it would be a five-fight win streak only for my hands, but it would mean the world to me to fight on the main card in Dublin in November.”
