The 2002 FIFA World Cup, in which the United States unexpectedly made the quarterfinals, coincided with a resurgence in American soccer and MLS. MLS Cup 2002 drew 61,316 spectators to Gillette Stadium, the largest attendance in an MLS Cup final until 2018. MLS limited teams to three substitutions per game in 2003, and adopted International Football Association Board (IFAB) rules in 2005.
