War on I-4 participant University of Central Florida
The War on I-4 is a college rivalry between the University of Central Florida Knights and University of South Florida Bulls. The rivalry is best known for its college football matchup which originated in a series of football games played from 2005 to 2008 and now takes place on Thanksgiving weekend, the de facto "rivalry weekend" for FBS football. In 2013, when UCF joined the American Athletic Conference, the schools began competing annually in all sports. In 2016, the schools officially adopted the "War on I-4" as an official competition series. Each year, the team with the most wins across all sports receives a gold trophy styled after an Interstate 4 (I-4) road sign with the logos of each school. The winner of the annual football game also receives a similar trophy.
As of April 24, 2023, South Florida holds the all-time series lead for seven of the ten sports in which the schools meet head-to-head: baseball (84–81), men's basketball (27–19), women's basketball (32–17), men's soccer (29–9–4), men's tennis (36–13), women's tennis (20–11) and volleyball (49–45); but UCF disputes the all time records in baseball, women's basketball, men's soccer, and volleyball, claiming the Bulls' records in these sports are 81–80, 29–14, 28–9–4, and 47–44, respectively. The only sports where UCF leads the all time head-to-head series are women's soccer (12–6–4), softball (23–19), and football (8–6). UCF leads the all time trophy series 6–0. The Knights have also lead overall since both schools joined the American Athletic Conference with a 123–81–4 record in conference games against the Bulls across all sports, whereas the all-time total across all sports is 307–237–8 in favor of the Bulls. The Knights lead 11–10–2 all time in conference tournament matches and the teams are tied 4–4–1 in conference championship games (though USF has actually won five conference championships head-to-head against the Knights; the tie denotes that their 2017 women's soccer title was won on penalty kicks). The Bulls are 6–4 against UCF in NCAA tournament games, making the overall postseason total 16–15–2 in favor of the Bulls.
