The 1997 Cincinnati Bengals season selected Dillon in the second round of the 1997 NFL Draft, the 43rd overall pick and the fifth running back. During his first season in 1997 Cincinnati Bengals season, Dillon rushed 39 times for 246 yards and 4 touchdowns in a 41-14 win over the Tennessee Titans breaking Jim Browns rookie single game record that had stood for  and remains a Bengals rookie record for carries, yards, and touchdowns, and franchise record for touchdowns. His 1,129 yards that season is also still a Bengals rookie record. For six seasons, Dillon was one of the few bright spots on otherwise struggling Bengals teams. Dillon voiced his frustrations with the team and owner Mike Brown (American football executive), stating "we will never win with the Brown family in Cincinnati," after a 2001 game. From 1997 to 2002, he rushed for over 1,000 yards each year, and made the Pro Bowl 3 times (1999-2001). On October 22, 2000, Dillon set an NFL record for most yards rushed in one game (278 yards) against the Denver Broncos, breaking Walter Paytons single-game mark of 275 yards set on November 20, 1977. The record has since been broken by Jamal Lewis (295 yards) on September 14, 2003, and Adrian Peterson (296 yards) on November 4, 2007; it remains a franchise record for yards and yards-per-carry (12.64).
Question: How many years after Dillon's record of most yards rushed in one game did Adrian Peterson break the record?
