The Massillon Tigers were an early professional football team from Massillon, Ohio. Playing in the "Ohio League", the team was a rival to the pre-National Football League version of the Canton Bulldogs. The Tigers won Ohio League championships in 1903, 1904, 1905, and 1906, then merged to become "All-Massillons" to win another title in 1907. The team returned as the Tigers in 1915 but, with the reemergence of the Bulldogs, only won one more Ohio League title. Pro football was popularized in Ohio when the amateur Massillon Tigers hired four Pittsburgh pros to play in the season-ending game against Akron. At the same time, pro football declined in the Pittsburgh area, and the emphasis on the pro game moved west from Pennsylvania to Ohio.
