Kurtis Eugene Warner (born June 22, 1971) is a former American football quarterback. He played for three National Football League (NFL) teams: the St. Louis Rams, the New York Giants, and the Arizona Cardinals. He was originally signed by the Green Bay Packers as an undrafted free agent in 1994 after playing college football at Northern Iowa. Warner went on to be considered the best undrafted NFL player of all time, following a 12-year career regarded as one of the greatest stories in NFL history.

Warner announced his desire to return to the Cardinals for the 2009 season. The Cardinals offered him a two-year contract worth around $20 million but Warner was looking for a contract that would pay him about $14 million a year and the two sides could not come to an agreement. On February 27, 2009 Warner became a free agent and went on to have talks with the San Francisco 49ers. The 49ers offered Warner a contract worth more than that offered by the Cardinals. On March 4, Warner re-signed with the Cardinals to a two-year deal worth $23 million total, $4 million for each of the next two years, with a $15 million signing bonus, and $19 million guaranteed. Warner underwent arthroscopic hip surgery to repair a torn labrum on March 17, 2009. On September 20, 2009, Warner broke the NFL's single-game record for completion percentage in the regular season, completing 24 of 26 passing for 243 yards and two touchdowns. Warner's 92.3 percent completion rate broke the previous NFL record set by Vinny Testaverde in 1993.  On November 1, 2009, Warner threw a career-high-equaling five interceptions during a loss to the Carolina Panthers. During the same game Warner became the first quarterback in the NFL to throw for over 14,000 yards with two different teams. On November 8, Warner equaled his career-high of five touchdown passes in a single game during a 41-21 victory over the Chicago Bears. This performance led to Warner being named both the NFC Offensive Player of the Week and the FedEx Air NFL Player of the Week. On November 15, 2009, Warner reached a career milestone with his 200th touchdown pass during a 31-20 win against the Seattle Seahawks.  On November 22, 2009, during a 21-13 victory over the St. Louis Rams, Warner left the game after suffering a concussion. Warner continued to suffer from post-concussion symptoms and on November 29, 2009, he was deactivated against the Tennessee Titans, breaking his consecutive starts streak at 41 straight games. On December 6, 2009, Warner returned to action as the Cardinals defeated the Minnesota Vikings 30-17. Warner registered his fourth consecutive game with a passer rating of 120 or better, making him only the second quarterback in NFL history to accomplish the feat. After his three-touchdown performance, Warner was named both the NFC Offensive Player of the Week and the FedEx Air NFL Player of the Week.  On December 27, 2009, Warner became only the second quarterback in NFL history to throw 100 touchdown passes with two different teams (Hall of Famer Fran Tarkenton is the other), in the Cardinals' 31-10 win over the St. Louis Rams. On December 29, 2009, Warner was named an alternate quarterback for the NFC team in the 2010 Pro Bowl.
