Jarrod Mullen (hamstring) and Peter Mata'utia (knee) were both sent for scans on Tuesday after suffering injuries in Monday's loss at Hunter Stadium.
Mullen has a high grade hamstring strain, however the five-eighth will need to see a specialist to determine treatment for a tendon injury.
For Mata'utia, scans confirmed a medial collateral ligament (MCL) and meniscus injury to his knee. The injury is expected to keep Mata'utia out for approximately eight weeks.
UPDATE: Jarrod Mullen is scheduled to see a specialist on Friday for a hamstring tendon injury. More details regarding his rehabilitation process will be known thereafter.
