The Chicago Rush is a team in the Arena Football League. They began play as a 2001 expansion team.
The team made its AFL debut in 2001. Although their administrative offices are based in Des Plaines, Illinois, northwest of Chicago and near O'Hare International Airport, the team plays its home games in neighboring Rosemont, Illinois at Allstate Arena (formerly known as the Rosemont Horizon), the same venue previously used by the Chicago Bruisers, one of the four original Arena Football League teams. The Rush compete in the Central Division of the American Conference. Former Chicago Bears coach and player Mike Ditka is a co-owner of the team.
The Rush have made the playoffs every year in the franchise's short history, and so far, they have made one ArenaBowl appearance. In their inaugural year (2001), the Rush won their very first playoff game, beating the Orlando Predators 41-26, but lost to the eventual ArenaBowl XV champion Grand Rapids Rampage 53-21. In 2002, the Rush won the Central division and received a bye in the playoffs. They defeated the Dallas Desperados 60-47, but fell in the semifinals to the Arizona Rattlers 46-35. In 2003, the Rush had a .500 regular season, yet got into the playoffs. They fell in Round 1 to the New York Dragons 48-45. In 2004, the Rush won the Central division with an 11-5 record. They won their first round game 59-49 over the Orlando Predators, but they fell in the semifinals to the eventual ArenaBowl XVIII champion San Jose SaberCats 49-35. In 2005, they went to the AFL playoffs as the #3 seed in the American Conference. They won the conference semifinal over the Los Angeles Avengers 52-45, but ended up losing the American Conference Championship Game to the eventual ArenaBowl XIX Champion Colorado Crush in overtime, with a final score of 49-43. That game became known as the "Confetti Game", due to an arena employee firing a confetti cannon prematurely, when the game was extended due to a defensive penalty on the final play. After a ten minute delay to clean the confetti, the Rush were able to tie the game on the untimed down, forcing the overtime period.
