(CNN)Sitting on the floor, Morteza Mehrzadselakjani's raised arms stretch well over six feet.
Standing up, the Iranian Paralympian measures eight feet one inch, making him the tallest athlete in the history of the Paralympics and the joint second tallest man in the world.
At eight feet two inches, only Turkey's Sultan Kosen is taller.
Sitting volleyball star
While his height has caused Mehrzadselakjani -- known better as Mehrzad -- anguish and suffering his entire life, on the sitting volleyball court it has made him a star.
When he was substituted on in the third set of Wednesday's group B match against Ukraine, the crowd at the Riocentro Pavilion exploded.
