A team captain is identified by the letter “C” on an NFL player’s jersey. While teams have been naming captains privately for years, the league began recognising them officially in 2007, allowing up to six players per team to wear the captain’s “C” on their jerseys.
The “C” patch also has a series of stars beneath it that represent the amount of years a player has held the position. One star is filled in gold for each extra year of service as a captain.
Because some teams opt out of the NFL’s system, their players do not wear the “C” patch. These teams choose their own captains using an internal mechanism, such as rotating captains week to week.
