The Bears and police said that the fan, 58-year-old Richard Kohnke of New Orleans, was one of several Saints fans who McCaskey found sitting in his seats when he arrived. After McCaskey briefly spoke to one of them and headed to find stadium security, Kohnke "went after" McCaskey and pushed him in the back.
Chicago said Kohnke was then tackled by a Bears fan. Kohnke was ejected and charged with simple battery.
The Bears said McCaskey did not need medical attention.
The Saints won the game 31-15.
