The Penrith Panthers are sweating on the fitness of captain Isaah Yeo, with the star lock set to undergo scans on Sunday to determine the extent of an injury suffered against the New Zealand Warriors.
Yeo sustained the injury during Friday night's nail-biting loss to an impressive Warriors outfit in Auckland, with the Panthers confirming the results of his scans are expected to be known on Monday.
The injury is currently suspected to be a pectoral issue, which could potentially rule Yeo out for the remainder of Penrith's season.
Isaah Yeo is off & wont return after suffering a reported shoulder or pec injury - will go for scans to confirm severity.

Such an outcome would be a significant blow to the Panthers' premiership campaign, with Yeo playing a crucial role in the side's success and leadership throughout the season.
The 31-year-old also risks missing out on the Rugby League World Cup, which is scheduled to begin in October.
Penrith will now wait anxiously for the results of Sunday's scans, with the extent of Yeo's injury set to determine both his club and representative prospects for the remainder of 2026.
