The Steagles, officially known as the Phil-Pitt Combine, was the team created by the temporary merger of Pennsylvania's two National Football League (NFL) teams, the Pittsburgh Steelers and the Philadelphia Eagles, during the 1943 season. The two franchises, due to both having many players leave for military service during World War II, were compelled to field a single combined team. The league's official record book refers to the team as the "Phil-Pitt Combine", but the unofficial and portmanteau variation of the "Steagles", despite never being registered by the NFL, has become the enduring moniker.
