Rostov Don defeated FTC, but somehow referees did not see THIS

In the match Rostov Don against Ferencváros happened the episode you can see on this photo, made by a supporter meanwhile watching it on television!

Referees, EHF delegate and officials did not observe that Rostov Don had EIGHT players on the court after the last timeout, when 21 seconds was to play of the match. Lunde was sitting on the bench and Borschenko had the goalkeeper shirt.The other seven players for the hosts on the court were: Anna Sen, Ekaterina Ilina, Yulia Managarova, Vladlena Bobrovnikova, Elena Avdekova, Maja Petrova and Elenea Slivinskaja.

The Rostov did not manage to score, even they were 8 players, but they lost the ball. At return they were one player more to defend against the possible FTC attack and a possible scoring. The match ended 23-21.

There are new rules in handball??? Or we need new rules??
