The 21-year-old forward has joined the Tabriz-club football team on a three-year contract.
Shekari made a name for himself four year ago when he scored his first professional goal in a match against Persepolis in Hazfi Cup, where Zob Ahan won the game 2-0.
He joined Rubin Kazan U-21 team in 2017 and made his Russian Premier League debut in April 2018 in a game against FC Akhmat Grozny.
Persepolis had reportedly reached an agreement with Shekari but the player opted Tractor Sazi for the new season.
