One remnant of the Bears' time at Wrigley was uncovered during the off-season 2007–2008 rebuilding of the playing field: the foundations for the goal posts. Five NFL championship games were played at Wrigley Field; 1933, 1937, 1941, 1943 and 1963. Coupled with the Chicago Bears, the Chicago Cardinals of the National Football League called Wrigley Field home from 1931-1938. Born on the South Side of Chicago, the Cardinals also played their home games at Normal Park, Comiskey Park, and Soldier Field.
