Wigan Warriors have made one change to their 21-man squad for Thursday's clash with Hull FC, with club captain Tommy Leuluai dropping out.
Leuluai suffered a sternum injury last week which ruled him out of the Warriors' victory against Castleford Tigers, and he will once again miss out this week as Wigan aim to preserve their unbeaten record against a Black and Whites side also yet to taste defeat in 2021.
Leuluai has been replaced in the squad by youngster Sam Halsall, with Lam likely to name an unchanged 17 from the one that ended Castleford's winning start to the season last week. Sam Powell and Liam Farrell are the likely candidates to captain the Warriors in Leuluai's absence.
The game has come too soon for winger Dom Manfredi, who is closing in on a return from a hand injury which has kept him on the sidelines so far this season.
“He looked like he may have been alright this week, but we feel it’s not something to rush into," Lam said. “We’ve got to make sure he’s absolutely right when he plays. We understand just how important he is to us, but we must air on the side of caution.”
Hull FC have made two changes to their 21-man squad. Bureta Faraimo and Josh Bowden have been ruled out due to suspension and injury respectively, and they are replaced by Jack Brown and youngster Harvey Barron, who is named in Hull's squad for the first time in his career.
Wigan 21-man squad: Bevan French, Zak Hardaker, Brad Singleton, Sam Powell, Joe Bullock, Willie Isa, Liam Farrell, John Bateman, Oliver Partington, Morgan Smithies, Tony Clubb, Liam Byrne, Harry Smith, Ethan Havard, Jake Bibby, Mitch Clark, Joe Shorrocks, Sam Halsall, James McDonnell, Umyla Hanley, Jackson Hastings.
Hull FC 21-man squad: Jake Connor, Carlos Tuimavave, Josh Griffin, Mahe Fonua, Marc Sneyd, Scott Taylor, Danny Houghton, Chris Satae, Andre Savelio, Ligi Sao, Jordan Johnstone, Joe Cator, Jordan Lane, Brad Fash, Ben McNamara, Jack Brown, Adam Swift, Cameron Scott, Jude Ferreira, Mitieli Vulikijapani, Harvey Barron.
