Dmitri Uchaykin, a Russian forward for the Ertis Pavlodar club, was 32. His club announced the death on its website, but did not give further details.
Uchaykin took a hard hit from Arystan forward Donatas Kumeliuskas during their game, but Russia's Sovetsky Sport said the player left the ice on his own and drove back home after the game. It said he then lost consciousness the next day and was rushed to a local hospital, where he died of a stroke early Sunday.
Uchaykin has spent most of his career with Russian club Amur.
