The Spokane Chiefs will know in about three hours whether their Western Hockey League season is over or if it extends at least another three days. The Chiefs trail the Portland Winterhawks 3-0 in their best-of-seven Western Conference semifinal heading into tonight's Game 4 at the Arena. If Spokane wins tonight, it will play Saturday at the Rose Garden in Portland. Game 6 would be back in Spokane on Monday. Todd Fiddler, Spokane's leading goal-scorer during the regular season, and Jackson Playfair have been scratched for the game. Stewart Coyle and Markson Bechtold will take their place. Game time is 30 minutes away.
