In 1971, ABA commissioner Jack Dolph left his briefcase open courtside during the ABA All Star game exposing pro contracts for two college basketball players who still had eligibility. The contracts were noticed and led to an NCAA investigation. When the investigation ended, Villanova had its entire season vacated while Western Kentucky had its postseason erased.

In 1983, Swedish tennis star Bjorn Borg retired surprisingly after a 16-month absence.

In 1944, the Detroit Red Wings beat the New York Rangers 15-0 in what is still the largest margin of victory in the NHL.
