A Phoenix spokesman said an extra player may be signed to the roster but any player decisions would have to go through head coach Ricki Herbert who is away on international duty in China with the All Whites this week.
The club have continued to remain tight-lipped about the `medical condition' that hindered Pavlovic.
He made a limited impact and in 25 appearances for the club - 24 of which were from the bench - he scored two goals.
He was one of only six Phoenix players to have been shown a red card after he was given his marching orders for a reckless challenge on Perth's Steve Pantelidis during a game in December last year.
Pavlovic also broke his arm in September last year after attempting an overhead kick at the end of training, which ruled him out for two months.
Up front the Phoenix have former Belgian international Stein Huysegems, All White Jeremy Brockie and 17-year-old Tyler Boyd, while Benjamin Totori has also been used as a striker this season.
Ricardo Clarke, who is on loan from Panama outfit Sporting San Miguelito, is also available but has played only one game from the bench this year.
Of the potential replacements, school of excellence player Tom Biss shapes as a solid option given his impressive debut against Melbourne Heart in week two when the Phoenix were without a host of players due to international commitments.
