changed from aqua to white. The Minnesota Vikings introduced a slightly tweaked "Norseman" logo and unveiled new uniforms. The colors are barely changed, with a new font for the uniform numbers and asymmetrical stripes on the pants. The new helmets feature matte purple paint with glossy logos and black facemasks. The San Diego Chargers introduced some relatively minor uniform alterations. The most noticeable change is the switch to "self-color" collars (where the collars match the jersey body) from the previous contrasting color "neck roll" collar design. There were also some changes to the colors used on the nameplates as well as some changes to the socks. The pants and helmets remain unchanged. The New York Giants introduced a new alternate uniform consisting of new white pants which may be worn with the team's existing blue jerseys in place of the usual grey pants. The team wore this new alternate uniform on November 10 against the Oakland Raiders and November 24 against the Dallas Cowboys. In honor of the fifteenth anniversary of the team's relocation to Nashville, the Tennessee Titans wore their alternate navy blue jerseys in two home games. This marked the first time since that the Titans wore the navy blue jerseys which were their primary home jerseys in their early Tennessee seasons before they switched to their current light blue jerseys. The Titans also added a patch commemorating the 15th season in Tennessee to their jerseys. The Indianapolis Colts added a jersey patch which celebrates the team's 30th season in Indianapolis. Due to a new recommendation that a player should use the same helmet for all games, several teams were forced to make changes in their plans to use alternate and throwback jerseys, including the following: The Tampa Bay Buccaneers shelved their "Creamsicle" throwback uniforms completely. The Patriots similarly chose not to wear their throwback uniforms at all in 2013. The Washington Redskins wore their current helmets (with the center stripe decal removed) along with their throwback uniforms which feature a different shade of burgundy. The Green Bay Packers also wore their current helmets with their throwback uniforms, but with the stripes and logo decals removed. The Dallas Cowboys decided to wear their blue "away" jerseys at their Thanksgiving Day home game, something they have not done since the 1960s. Traditionally the team has worn their throwback jerseys (which include a white helmet) for the Thanksgiving game. U.S.
