The Manchester United loanee has been limited to just a few minutes of playing time due to fitness and form issues.
Sancho's only start for the team was in the Carabao Cup match against Brentford, which Villa lost.
He had been training separately from the senior squad due to illness, but has now recovered and aims to be available for Villa's next match against Tottenham after the international break.
Aston Villa has experienced a resurgence in form, winning their last three Premier League games after a slow start to the season.
