The Browns joined the NFL prior to the 1950 season, having won all four All-America Football Conference championships.

Some established NFL executives, coaches and players ridiculed the Browns for having dominated what was considered an inferior league. As if to remind the Browns that they didn't really belong, the NFL scheduled Cleveland to play its first regular season league game against the two-time defending champion Eagles on Sept. 16, 1950 in Philadelphia.
