Sprint football
Sprint football, formerly called lightweight football, is a varsity sport played by United States colleges and universities, under standard American football rules.  The sport has two governing bodies—the Collegiate Sprint Football League, founded in 1934, and the Midwest Sprint Football League, founded in 2021 ahead of its first season in 2022. In all, 16 schools field sprint football teams—eight each in the CSFL and MSFL.
