The 29-year-old striker is currently undergoing a severe program with the team's physio Tarek Abdul-Aziz.
Fadl did not feature in any of Ahli's pre-season matches due to the niggling injury, which saw him miss long spells of last term.
Meanwhile, striker Ahmed Belal has suffered a minor groin injury, following his recent return to full training.
Belal also missed the Red Devils' recent games with Celtic and Barcelona in the Wembley Cup.
