Becky Lynch and Liv Morgan will battle for a Women’s World Championship opportunity when WWE Raw heads to St. Louis on Monday, October 5.

The winner will challenge Stephanie Vaquer at Money in the Bank just five days later. Roman Reigns is also set to return as WWE puts the finishing touches on Raw’s build to Saturday’s event.

Raw General Manager Adam Pearce confirmed the line-up in his weekly preview, with the show airing live from the Enterprise Center at 8 p.m. ET / 5 p.m. PT on Netflix.

“We will determine a number one contender to Stephanie Vaquer and her Women’s World Championship, because Liv Morgan battles Becky Lynch live on the flagship,” Pearce said.

Lynch and Morgan have unfinished business following WWE’s September 12 live event in Santiago, Chile. With Lynch serving as special guest referee, Morgan appeared close to retaining her championship after hitting Vaquer with Oblivion. However, Lynch stopped counting at two.

Morgan confronted Lynch, opening the door for Vaquer to take the championship and end Morgan’s 147-day reign. The victory marked Vaquer’s second run with the title after losing it to Morgan at WrestleMania 42.

Morgan has yet to receive a rematch, but beating Lynch would give her the chance to reclaim the gold in New Orleans.

Meanwhile, World Heavyweight Champion Roman Reigns will make his first Raw appearance since September 14, with LA Knight waiting for him at Money in the Bank.

“Between The 946 and the Bloodline and LA Knight, your World Heavyweight Champion, the OTC Roman Reigns, has a lot on his mind,” Pearce said. “And I’m sure we’re going to hear all about it live tomorrow night in St. Louis.”

Knight attacked Reigns with a BFT after Raw went off the air in Mexico City, following the champion’s successful defence against Penta. Reigns subsequently accepted Knight’s challenge, setting up their championship showdown.

Monday’s show will also bring several Money in the Bank opponents together in tag team action.

Penta and Je’Von Evans will face World Tag Team Champions Bron Breakker and Austin Theory. Penta, Evans and Breakker are all entered in the men’s ladder match, giving each a chance to build momentum before Saturday.

Penta secured his place after replacing Solo Sikoa in a September 21 qualifier, following Sikoa’s abduction by The 946.

In the women’s division, Sol Ruca and Lola Vice will team up against Raquel Rodriguez and Roxanne Perez. Ruca, Vice and Perez will then compete against one another in the women’s Money in the Bank ladder match.

AAA World Cruiserweight Champion Rey Fenix is also scheduled to face Ethan Page.

“You saw him run his mouth, yeah I’m talking about Ethan Page,” Pearce said. “Now he’s gonna have to back it up when he goes one-on-one with Rey Fenix.”

The announced Raw line-up is:

• Becky Lynch vs. Liv Morgan to determine Stephanie Vaquer’s Women’s World Championship challenger.

• Penta and Je’Von Evans vs. Bron Breakker and Austin Theory.
