Injury-ravaged Adelaide United have lost attacking midfielder Kristian Sarkies for the rest of the A-League season.
Sarkies has been in hospital since Saturday with a blood clot in his left arm and will be sidelined for at least two months.
Adelaide has also ruled out striker Dez Giraldi from the team to play Newcastle on Friday night.
Giraldi suffered heart palpitations and was a late withdrawal from Adelaide's lineup which lost to Sydney last Friday.
The Reds will also be without defenders Robert Cornthwaite and Cassio against Newcastle as both serve one-match suspensions.
Sarkies, who scored his first goal for Adelaide United against Sydney, is expected to be released from hospital later this week.
"We had a drinks break 20 minutes into the game (against Sydney FC), that's when I told the doctor that my arm was about to explode," Sarkies said on Wednesday.
"I felt it about a week and a half ago when I slept with my arm above my head and woke up with a sore neck and sore shoulder - I pretty much thought nothing of it."
Giraldi has been cleared of heart problems by cardiologists, who believed he had an anxiety attack.
Adelaide's injury list already included captain Mike Valkanis (knee), Paul Agostino (thigh), Nathan Burns (hamstring), Shaun Ontong (ankle), Daniel Beltrame (quadricep) and Jason Spagnuolo (knee).
Of those, Valkanis and Ontong won't play again this season with Burns and Agostino unlikely to return. Beltrame and Spagnuolo should resume in a week.
To cover the injury crisis, Adelaide has re-signed midfielder Fabian Barbiero for the next three matches and 18-year-old defender Daniel Mullen for one match.
