The players, Enoch Maki, Anderson Benford and Brandy Peter have recently undergone surgery.
Maki is faced with a knee injury while Benford is struggling with an injured foot and both have had surgery in Australia and are now back in Moresby undergoing rehabilitation to get back on track.
Peter was faced with a fractured hand and also had an operation last week and will be on the bench for three weeks.
Coach Michael Marum said they are on the road to recovery and should be back on the field before the season kicks off.
