Iman Heidari struck with 20 minutes remaining to rescue a 1-1 draw for Shahin FC and deny Iran Pro League leaders Zob Ahan victory on Sunday.

Mehdi Rajabzadeh gave the AFC Champions League semi-finalists the lead in the 45th minute but Heidari equalised in the 70th minute to earn a point for the hosts.

The draw means Zob Ahan extend their lead at the top of the standings to three points after second-placed Persepolis lost 3-2 at home to Malavan. Pejman Noori scored with three minutes remaining to hand the visitors all three points and condemn Persepolis to their second defeat of the season.

Elsewhere, third-placed Esteghlal drew 1-1 with Saba Battery while Sepahan claimed a 5-0 win over Steel Azin. Finally, Teraktor Sazi beat Naft Tehran 3-1 while Shahrdari Tabriz edged Saipa 1-0.
