Fox Sports' Jordan Schultz reported Monday the NFL is altering its uniform policy to allow teams to wear their throwback and alternate jerseys more often in the future. The new policy will permit teams to wear such uniforms up to four times throughout a single season.

Jordan Schultz of Fox Sports reports that the NFL is updating its uniform policy to allow teams to wear throwback or alternate uniforms up to four times per season. Philadelphia last wore Kelly Green jerseys (and helmets) in the 2010 season. Shortly after, the NFL implemented a rule requiring teams to have only one color as a safety precaution.

Each team has what the NFL likes to call a closet. Each team has a "primary" section that consists of the usual home and away uniforms. Some teams have an alternate uniform (think Color Rush.) And then some teams have their throwbacks, or what the league calls "classic" uniforms.
