Iran Pro League leaders Zob Ahan extended their advantage at the top of the table to four points - but they needed a last-minute goal from Seyed Farimani to claim a 2-2 draw at Rah Ahan on Thursday.

The visitors had gone in front after just three minutes through Mohammad Ghazi but Rah Ahan fought back in the second half as efforts from Iman Razaghirad and Meysam Aghaei put them in control with just seven minutes to go. But Farimani's late intervention ensured Zob Ahan snatched a point.

Elsewhere, Saipa and Esteghlal played out a goalless draw.
