Carroll, who played for Reading and West Brom last season, has reportedly turned down huge money to join Tractor.
According to the MailOnline, ex-England, Liverpool and West Ham man Carroll has rejected a move to Iranian side Tractor after he was offered a one-year contract on around £20,000 a week.
Carroll has been without a club since his seven-month stay at West Brom came to an end in the summer.
