Philly Mettle on Instagram: "Flyers vs the Red Army was a famous international hockey game where CSKA Moscow walked off the ice in the first period in protest after the referees did not call a penalty on Flyers Ed Van Impe for his hit on Valeri Kharlamov. Eventually the Russians were persuaded to come back on the ice, and they lost to the Flyers 4-1. #philadelphia #flyers #bestofphilly #1970sstyle #philly"
