The NFL on Monday expanded the number of times that teams can wear alternate or throwback uniforms in a given season. The prior limit was three; the new maximum is four. Last year, the NFL increased the number of different helmets a team can wear in the same season to three.

Thanks to the NFL's updated uniform policy, the Baltimore Ravens could wear Purple Rising or All-Black alternate jerseys four times per season.

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.
