Iran need a win over Portugal to qualify for the second round, but Ricardo Quaresma's outside-of-the-right-foot effort has beaten Iranian keeper Alireza Beiranvand to give Portugal a 1-0 lead at half-time.
Second half commences with Iran making efforts to get an equalizer, but Portugal are awarded a penalty after a VAR replay showed Cristiano Ronaldo was fouled in the 53rd minute.
Ronaldo's kick is saved by keeper Beiranvand.
Cristiano Ronaldo has become the fifth player to miss a penalty at this World Cup.
Iran keep pushing for an equalizer.
