"The enemy had placed explosives on a motorbike and detonated it on the edge of the volleyball playground," said Zarawar Zahid.
There were conflicting reports about whether volleyball, cricket or football was being played at the time. The Taliban has denied that it attacked the game
Last November, at least 50 people were killed in an attack on a volleyball match in Paktika.
Earlier, a statement purportedly issued by an IS affiliate claimed a "big attack" had been carried out in Nangarhar, also bordering Pakistan and in an area IS refers to as Khorasan state.
A local official told the BBC earlier that government forces were resisting militant attacks in Achin district, and had killed 60 fighters.
