first set of Modena and Milano

Can someone please tell me what happened in the first set (score 11-9) of Modena and Milano? 
In the rally, all Milano players put their hands up complaining about an action of Zaytsev, the rally continued and Abdel-Aziz finished with hitting the ball of the block.
There was a challenge and Modena won the point.. but i couldn't hear or see the result, just Modena won?
