The Poland worldwide limped off after coming on as a second half substitute in Saturday's 3-2 win at Serie A new boys SPAL to help preserve their 100 per cent start in the league. The injury resulted in the Poland global missing 21 games for the Serie A giants.
Milik moved to Naples from Ajax before the start of last season but was sidelined between October and February after damaging his anterior cruciate ligament while on worldwide duty.
Milik, who has played 91 Serie A minutes this season scoring one goal, was brought on for Napoli against Spal to replace midfielder Piotr Zielinski with 20 minutes left on the clock.
The Belgian has excelled as the focal point of Napoli's attack, although they could struggle with depth in the position with Milik now set for another extended absence.
The 25-year-old Chievo forward was bought this summer for €10 million but was left on loan at Bentegodi and could be recalled six months ahead of schedule to fill in for the Polish forward.
