Stars centre Peverley collapses
The NHL game between Dallas and the Columbus Blue Jackets was called off when Stars centre Rich Peverley collapsed on the bench.
Peverley had just left the ice when he slumped on the bench seven minutes into the game, before receiving treatment for what was described by one of the medics who treated him as a "cardiac event".
A statement from the NHL said the player was "doing well and is in a stable condition" and that the game was postponed "as a result of the emotional state of the players on both teams".
The New York Islanders scored all seven goals in the third period as they rallied to beat the Vancouver Canucks 7-4.
The Islanders were 3-0 behind before goals from Josh Bailey, Ryan Strome, Calvin de Haan and Frans Nielsen scored in a little over five minutes put them ahead.
Christopher Tanev responded for the Canucks but further scores from Matt Martin, Anders Lee and Cal Clutterbuck finished them off.
Chris Kunitz scored twice as they Pittsburgh Penguins claimed a 3-2 victory over the Washington Capitals.
Sidney Crosby also scored, while Eric Fehr and Nicklas Backstrom tallied for the Capitals.
