In 1998, Warner was finally signed by an NFL franchise, the St. Louis Rams, and was allocated to NFL Europe's Amsterdam Admirals, where he would lead the league in touchdowns and passing yards.[15] Incidentally, his backup at the time was future Carolina Panthers quarterback Jake Delhomme, another famous rags-to-riches quarterback story. Returning to the United States for the season, Warner spent the 1998 season as St. Louis' third-string quarterback behind Tony Banks and Steve Bono. He ended his season completing only 4 of 11 pass attempts for 39 yards and a 47.2 QB rating.
After releasing Banks and Bono following the 1998 season, the Rams signed free agent Trent Green to be their starting QB, and Warner was promoted to second string. When Green tore his ACL in a preseason game, Warner took over as the Rams' starter.
