In 1962, University of Florida put the Confederate Battle Flag on the side of their helmet for one game.
That game was the 1962 Gator Bowl vs Penn State. Florida was 6-4 and Penn State was 9-1 and Penn State felt that playing Florida was a slap in the face since they were 9-1. Since Penn State felt that way Florida put Battle Flags on the side of the helmet to pump the team up. It worked when Florida won 17-7.
It has not been confirmed if the stripe was orange, royal blue or navy blue
