Bosnia-Hercegovina boss Safet Susic may opt to recall striker Vedad Ibisevic, who began their first two matches on the bench.
The tournament debutants have been eliminated but will target their first World Cup points.
Iran coach Carlos Queiroz is unlikely to make many changes following their impressive display in the 1-0 defeat to Argentina.
The Iranians must win to have any chance of reaching the last 16 BBc reports.
