The Pennsylvania Polka refers to a series of moves affecting the Philadelphia Eagles and Pittsburgh Steelers franchises in the National Football League (NFL) from 1940 to 1941. Art Rooney, the owner of the Pittsburgh Steelers, sold his team to Alexis Thompson on December 10, 1940, and subsequently bought a 50% stake in the Philadelphia Eagles franchise from owner Bert Bell. At the time of the deals, a mini-draft took place between the two teams, using a pool of players from both rosters. This resulted in the Eagles acquiring seven players formerly of the Steelers, and the Steelers obtaining eleven players formerly of the Eagles. The 1941 NFL Draft was also held during this time.
