Iran's nail-biting World Cup qualifier against Syria in Tehran's Azadi stadium was notable for more than just the last-minute equaliser by the visiting team.
The presence of at least two female lawmakers was thought to be the first time Iranian women were allowed to watch a men's match since the 1979 Islamic revolution.
The next day, the ISNA news agency said the stadium website had been hacked, with a banner placed across the front page for several hours saying: "Let Iranian women enter their stadiums".
Some women MPs rejected the offer.

"At a time when girls of this country have no choice but to dress as men to get into the stadium, I as a representative of these people would not like to be present in the stadium by receiving a special permit," Parvaneh Salahshouri, another member of parliament, told the reformist Shargh newspaper.
"I go in when they too can come in," she said.
But Siavoshi accepted the invitation, saying it was a sign of progress.
Sports Minister Masoud Soltanifar suggested further change could be coming.
"We will try to pave the ground for the presence of families in stadiums by consultation and coordination," he said, according to the Tasnim news agency.
"I am confident that the fans would respect boundaries which need to be respected."
Female foreigners are allowed to attend matches, and many noted the presence of Syrian women in the crowd at Azadi stadium on Tuesday night.
Women are not allowed to watch men's football - and some other sporting events such as wrestling - because the atmosphere is considered too vulgar for them.
Some gather outside the stadium during matches as a protest, while many also sneak through the gates in disguise.
