Teams are only permitted to wear alternate jerseys once in playoff games (except the Super Bowl, where teams must wear their standard uniforms); the only team to do so (other than in 1994) was the 2008 San Diego Chargers. In the past, rules allowed for teams to wear their third jersey two times in the regular season and once in the preseason until 2010. In 2011 teams were no longer allowed to wear their third jersey in the preseason.[7] However, there have been some exceptions since 2011.
