Iran have drawn 0-0 with 10-man Belgium as World Cup Group G becomes even tighter.
The Red Devils had defender Nathan Ngoy sent off for a last-man foul on Iran's Mehdi Taremi following a woeful back-pass on 66 minutes, but a stalemate remained and set up two crucial group finales.
Iran earlier thought they had taken the lead following a clever free-kick routine, but Taremi was deemed to be offside after a long video review.
Thibaut Courtois was also forced into two smart stops but otherwise Belgium dominated possession and chances, although they could not break through as Iran's defence put their bodies on the line.
In Belgium's 1-1 opener with Egypt, forward Romelu Lukaku had helped force the equaliser 22 seconds after climbing off the bench.
