April 9 American Football History Timeline
- On April 9, 1945, the NFL required players to wear long stockings. According to ESPN, Commissioner Elmer Layden mandated that NFL players wear their socks up to their lower legs, apparently for aesthetic and uniformity reasons. This rule, still enforced, explains why NFL players wear high socks while many NCAA teams play bare-legged. Displaying bare calves in the NFL can result in a fine from league headquarters. .
- On April 9, 1997, the NFL announced a $3 million loan to the CFL and discussions of a possible “World Classic Bowl”. The agreement was intended to reduce CFL hostilities regarding NFL games scheduled in Toronto as part of expansion plans. Toronto is the third-largest city in North America. The five-year partnership included the CFL granting the NFL permission to host annual preseason or regular-season games in Toronto or Vancouver during the agreement, per the Seattle Times.
- Jumping ahead to April 9, 2015, Hall of Famer Troy Polamalu retired after 12 seasons with the Steelers. Polamalu was selected to eight Pro Bowls, named first-team All-Pro four times, and was a two-time Super Bowl champion (XL and XLIII). He was the 2010 AP Defensive Player of the Year and played for the Steelers from 2003 to 2014.
