Tractor has almost missed the chance of winning the Iran football league for the first time.
Tractor lost to Zob Ahan 4-1 on Friday and is now 10 points behind leader Esteghlal.
With seven weeks remaining, Tractor sits third in the 2023-24 Iran Professional League (IPL) table with 40 points.
Tractor will face Nassaji in Matchweek 24 on Friday.
Jemez, 54, was appointed as Tractor coach in December 2022 but didn’t win a trophy with the club.
Former Persepolis coach Yahya Golmohammadi is a candidate to replace Jemez.
