Iranian middle blocker Seyyed Mohammad Mousavi has been ruled out of the 2017 FIVB Volleyball World League opening week due to a knee injury.

“Mousavi misses the first week of the competition since he is not fully-prepared. It's a huge blow for us ahead of the FIVB Volleyball World League but Iran has so many experienced players,” Iran volleyball manger Amir Khoshkhabar said.

Iran will take on Italy, Brazil and Poland on the first week of the competition, scheduled for June 2-4.

The matches will be held at the Adriatic Arena in Pesaro, Italy.

The 2017 FIVB Volleyball World League will be the 28th edition of the annual men's international volleyball tournament played by 36 teams between June 2 and July 2.
