Jack Duncan has become the second Australian goalkeeper in the past month to suffer a concussion playing in the Saudi Arabian Pro League.
The 25-year-old former Newcastle Jets keeper had to be replaced at half-time with concussion in Al Qadisiyah's 3-1 win over Al Raed over the weekend.
FTBL understands Duncan is now fine and hopeful of playing in his side's next league match against Al Faisaly on Friday.
Duncan has been in good form for the midtable Saudi club where he plays alongside ex-Perth Glory and Melbourne Victory defender Rhys Williams.
The concussion follows a nasty head injury to Socceroos goalkeeper Brad Jones earlier this month playing for Al Nassr.
Jones collided with a teammate and was left unconscious on the field, before being rushed to hospital in Al Nassr's 2-0 loss to Al Ahli.
The 36-year-old has returned to training but has had to miss his side's past two league matches and the recent Socceroos camp as he overcomes the symptoms.
