Three days before the 1972 Winter Olympics in Sapporo, controversy over amateur status arose when International Olympic Committee President Avery Brundage threatened to disqualify 40 Alpine skiers who received endorsement and other deals. Austrian skier Karl Schranz, who received over $50,000 per year from ski manufacturers, was banned as an example. Meanwhile, Canada refused to send an ice hockey team, maintaining that professional players from Communist nations were allowed to compete with no restrictions. It was the first time Canada had not been represented in the tournament since 1920 when ice hockey had made its debut as part of the Summer Olympics at Antwerp. They did not compete internationally again until 1977, when the International Ice Hockey Federation adopted eligibility rules that allowed for professional players to compete. Instead of playing at the Olympics, Canadian officials helped organise a series of games against the Soviet Union in 1972 known as the Summit Series.
