The 20-year-old, who suffered a knee injury on loan at Wolverhampton Wanderers last season, had been expected to return to action in pre-season.
However, according to The Sun, the Ghanaian will not return to training with the club until at least October.
Frimpong has made just six Premier League appearances for the Gunners.
