Petrov made his first Villa appearance in more than four years on Saturday after recovering from cancer.
The 37-year-old midfielder featured in the pre-season friendly match against Austrian sixth-tier club GAK 1902 on Saturday.
Villa won the game 8-0, with Petrov playing in the second half of the encounter.
The former Bulgaria international midfielder has been training with the Villans in pre-season and is hoping to return to the game in a professional capacity.
Villa will feature in the Championship next season after getting relegated from the Premier League at the end of the 2015-16 campaign.
The Villans will be aiming to finish in the top two of the league table during the 2016-17 season.
New manager Roberto Di Matteo has been quite busy in the summer transfer window so far, signing defender Tommy Elphick, goalkeeper Pierluigi Gallini and midfielder Aaron Tshibola.
