Scans have revealed the full extent of Moses Leota's shoulder injury suffered in the first-up victory over the Sea Eagles at BlueBet Stadium.
Leota fractured the glenoid in his left shoulder while making a tackle late in the game.
The affected area is the shoulder socket component of the scapula, which means the 26-year-old will commence a rehabilitation program and be sidelined for 8-10 weeks.
Leota's replacement for Friday's clash against St George Illawarra Dragons at Netstrata Jubilee Stadium will be announced when Panthers coach Ivan Cleary names his squad on Tuesday afternoon.
