Penrith playmaker Matt Moylan has not been named for Friday night's knockout NRL semi-final against Brisbane at Suncorp Stadium.
However, the Panthers could still apply for an exemption from the NRL to allow Moylan to make his comeback against the Broncos.
Moylan was again not picked by coach Anthony Griffin for the sudden-death clash after the Penrith skipper was granted personal leave by the club last week and underwent counselling.
But it's understood the Panthers are concerned about placing more pressure on the 26-year-old by naming him to play.
Under the NRL's team list guidelines introduced this year, only those named in a club's squad of 21 on Tuesday can play as part of the final 17 that round.
Players can only be brought into the squad when granted a special exemption by the NRL, usually in the case of any injury to a specialist position player.
Moylan's fitness may be another issue.
He has not trained with Penrith since being granted leave and is nursing a hamstring complaint that has restricted him to playing just two of the Panthers' last six games.
Meanwhile, Brisbane rolled the dice and named injured skipper Darius Boyd as 18th man.
Boyd will be given until the rest of the week to recover from the hamstring complaint that forced him to miss their qualifying final loss to the Sydney Roosters.
Explosive backrower Tevita Pangai Jr was also named in the extended squad after missing one week with a similar hamstring complaint.
Wayne Bennett has stuck Benji Marshall in the halves with Anthony Milford and Kodi Nikorima at fullback.
Parramatta have not named fullback Bevan French for Saturday night's semi-final with North Queensland at ANZ Stadium.
The livewire No.1 had been expected to make his return from a three-week hamstring injury but coach Brad Arthur has stuck with impressive replacement Will Smith.
Eels hooker Cameron King was named despite suffering an arm injury in last week's opening loss to Melbourne.
Scans have cleared King of a fracture but they did reveal nerve damage.
His fitness is expected to be assessed later this week.
