Panthers v Titans

Penrith could take the field without either of their starting halves, with James Maloney (Origin) and Nathan Cleary (injury) in doubt. Maloney is the more likely of the duo, with Cleary's injury ruling him out of Origin set to rule him out this weekend as well. Jarome Luai should start if either of the pair don't play.

Ashley Taylor is backing training with the Titans after taking personal leave, although he won't be considered for selection just yet. Tyrone Peachey should be fit to play.

Knights v Bulldogs

Lachlan Fitzgibbon will miss the next month after sustaining an elbow injury over the weekend. Edrick Lee underwent arm surgery and is aiming for a return in time for the finals, while Kalyn Ponga will need to spend another week on the sidelines as he battles a calf complaint. The Knights have lost four men to Origin, although they'll be hoping the quartet of Mitchell Pearce, Daniel Saifiti, David Klemmer and Tim Glasby can return.

Kieran Foran didn't run out last weekend's match, but is expected to overcome his hamstring injury and take the field this weekend. Jeremy Marshall-King should return from a knee injury and replace Michael Lichaa.

Rabbitohs v Sea Eagles

Sam Burgess should return from a shoulder problem for the hosts, while Alex Johnston could be in line for a comeback. Damien Cook, Cameron Murray, Dane Gagai and potentially Ethan Lowe will be involved in the Origin decider, and would need to prove their fitness before being named.

The Sea Eagles enjoyed the bye last weekend, with only the fitness levels of Origin trio Tom Trbojevic, Jake Trbojevic and Daly Cherry-Evans to worry about ahead of this clash.

Broncos v Warriors

Matt Gillett was ruled out of Origin on Tuesday, and would now be in doubt for Saturday's clash. Gehamat Shibasaki and Sean O’Sullivan will miss, meaning the Broncos could go with an inexperienced side once again. Cory Paix could debut.

Jazz Tevaga could miss with an ankle injury, with Lachlan Burr expected to take his spot if he can't play. Bunty Afoa and Peta Hiku will both be named, although the pair must pass concussion protocol before taking the field.

Storm v Sharks

The Storm should welcome back Origin players Josh Addo-Carr, Dale Finucane, Cameron Munster, Will Chambers, Felise Kaufusi and Christian Welch for Cameron Smith's 400th.

Paul Gallen is a chance to play, while Matt Moylan could be named as well despite hamstring troubles.

Roosters v Cowboys

Boyd Cordner and James Tedesco should back up, with Siosiua Taukeiaho set to return as well.

North Queensland may not make too many changes from their last fixture, with Michael Morgan and Josh McGuire set to back up from Origin. Matt Scott is a sneaky chance to play.

Tigers v Eels

Moses Mbye should back up after Origin, and would replace Paul Momirovski in the Tigers' side.

The Eels could go in unchanged, with Blake Ferguson's availability hinging on getting through Origin unscathed.

Dragons v Raiders

Tariq Sims will return from his one-match ban this weekend, which saw him ruled out of Origin III. Paul Vaughan, Ben Hunt and Corey Norman should all back up for the Dragons.

Nick Cotric could return from injury, while Jack Wighton and Josh Papalii will be keen to play following Wednesday night's Origin decider.
