Down 3-1 in the Eastern Conference Semifinal series with the Boston Bruins, the Philadelphia Flyers were already between a rock and a hard place. So this is the last thing they needed: Goaltender Brian Boucher left during the second period of Game 5 after teammate Ryan Parent fell on top of his leg while it was already pinned underneath him.
Chris Pronger helped him off the ice and Michael Leighton, who had just healed from a high ankle sprain which occurred on Mar. 16, filled in for Boucher. We're assuming that Miroslav Satan's presence in the crease was purely coincidental, and that he wasn't attempting devilish acts.
