it (nine was the number McNair wore during his time with the Oilers/Titans). From 2009 to 2012, the Titans did not wear an alternate jersey during any regular-season games. It was not until 2013 that the team wore the navy blue jerseys twice in honor of their 15th anniversary as the Titans. The Titans wore white jerseys for all games in 2014, for the exceptions of two preseason home games, in which the team wore their light Titans blue jerseys, and a game against the Houston Texans on October 26, 2014, in which the Titans wore their navy blue uniforms. Beginning in 2015, navy blue became the team's primary home jersey color again, marking the first time since 2007 that the Titans wore navy as their primary home jersey, though the team plans to continue wearing white jerseys for early-season hot-weather home games. The light Titans blue jersey, which was the team's primary jersey color from 2008 to 2014, became the team's alternate jersey for a second time. On April 4, 2018, the Titans debuted new uniforms at an event attended by over 10,000 fans in downtown Nashville. The uniforms retain the color palette of navy blue, Titans blue and white, with new red and silver elements being introduced. The new helmets are navy blue with one silver sword-shaped stripe through the center and metallic gray facemasks, a change from the previous white helmets with two navy stripes and black facemasks. Rivals The Titans share rivalries with their three AFC South opponents (Jacksonville Jaguars, Houston Texans, and Indianapolis Colts). They also have historical rivalries with former divisional opponents such as the Pittsburgh Steelers, Baltimore Ravens (formerly the original Cleveland Browns) and Buffalo Bills, and during their time as the Houston Oilers, shared an in-state rivalry with the Dallas Cowboys. Divisional rivalries Jacksonville Jaguars Since their founding, the Jaguars have been seen from time to time as the Titans' primary rival due to constantly competitive games between the two franchises. The rivalry began back in 1995 when the Titans were still called the Houston Oilers. The rivalry was heated in the late 1990s and early 2000s due to the success of both franchises at the time, including a season in which Jacksonville went 14-2 and Tennessee went 13–3. That season, all three of Jacksonville's losses (including the playoffs) came against the Titans, who went on to play in Super Bowl XXXIV.
