Edmonton, Alberta ? NHL hockey might turn a little bit colder.

The NHL is evaluating a proposal that could see the Edmonton Oilers play the Calgary Flames in an outdoor game in 2004.

League spokesman Frank Brown said the NHL is considering the idea of staging the game in 60,000-seat Commonwealth Stadium, but it is still far from becoming a reality.

Edmonton Mayor Bill Smith said the proposal has received tentative approval from both the league and the players’ association and the city is now in the process of working out a lease with the Oilers.
