An autopsy confirmed that NHL player Serge Zholtok died from heart failure after playing a game this week in Belarus.
Zholtok, 31, a forward for the Nashville Predators, was playing for a club in his native Latvia during the NHL lockout. He was diagnosed previously with an irregular heartbeat, a condition that forced him to miss seven games for the Minnesota Wild in January 2003.
Zholtok left Wednesday's game between Riga 2000 and Dinamo Minsk about five minutes before the end. He collapsed and died in the locker room.
Elsewhere, Vincent Lecavalier signed with a Russian team to play during the NHL lockout and said Tampa Bay teammate Brad Richards will be joining him.
