Picked up a fun fact from the NBA Encyclopedia: There is only one time in the history of professional sports that any player played for both teams in the same game. And that instance occurred in the NBA on this day in 1979, when the Philadelphia 76ers and the New Jersey Nets replayed the final 17:50 of their contest that was originally played on November 8, 1978 due to a protest being upheld.
When the game began on November 8, Harvey Catchings and Ralph Simpson played for the 76ers while Eric Money and Al Skinner played for the Nets. But all four were traded to the opposing teams by the time the Sixers-Nets game was resumed on March 23.
