It does appear that Perry, although starting in the crease, was able to move away from Vladar in time and the overhead shot looks like this was not a case of interference. According to Frank Seravalli, the NHL overruled the goal call on the ice, citing Rule 69.1 - Goals should be disallowed if the player either by position or contact impedes the goalies ability to move freely in the crease.
After this call and disallowed goal, Edmonton remained off the scoresheet, with the Flames winning the game 4-1. Perry's reaction to the no goal call was captured during the game, obviously showing his disapproval after a very lengthy review.
Perry, now at 39 years old, remained an Oiler for another year after there was so speculation he was going to retire. This season he has a bottom six role on the team, and so far, appears to be making a lot of noise that is not positive for Edmonton.
