Moses was named in Daley's squad on Monday despite having failed to play for the Eels since he was ruled out of the May 27 series opener in Sydney less than 48 hours before kick-off.
The Parramatta playmaker suffered a minor hamstring strain in the lead-up to game one and was replaced at five-eighth by Canberra's Ethan Strange.
Strange played a key role in the Blues' 22-20 victory but Moses' inclusion is expected to force the Canberra youngster to the bench for next Wednesday's clash at the MCG.
Dolphins halfback Isaiya Katoa has been called into the NSW squad as a reserve and will be on stand-by should Moses fail to prove his fitness.
Provided he encounters no further issues, Moses is likely to partner halfback Nathan Cleary as NSW look to clinch the series with a game to spare.
"If he finishes all his protocol for his hamstring, he'll be fine to play," said Eels coach Jason Ryles after his side's 14-12 loss to Canterbury on Monday.
"He didn't make it this week but had we been playing on Saturday or Sunday this week, I'm pretty confident he'd be playing for us."
Despite the Blues' struggling through the series opener until Kalyn Ponga's second-half send-off, Daley has resisted wholesale changes.
Daley released his team in alphabetical order on Monday evening and has brought just three fresh faces into his 20-man squad, with Origin rookie Katoa joined in the NSW set-up by Brisbane prop Payne Haas.
Broncos front-rower Haas will vie with Mitch Barnett and Addin Fonua-Blake for the two starting prop berths, with Newcastle's Jacob Saifiti dropping out of Daley's squad as a result of Haas's return.
Wests Tigers' Api Koroisau replaces injured Cronulla hooker Blayke Brailey and is in line for his first Origin appearance since 2023.Â
NSW SQUAD (alphabetical): Mitch Barnett, Nathan Cleary, Stephen Crichton, Addin Fonua-Blake, Payne Haas, Isaiya Katoa, Tolu Koula, Api Koroisau, Dylan Lucas, Casey McLean, Mitch Moses, Cameron Murray, Haumole Olakau'atu, Victor Radley, Reece Robson, Kotoni Staggs, Ethan Strange, James Tedesco, Brian To'o, Isaah Yeo (capt), Hudson Young.
