Last August IU played North Carolina in a game that drew more than 7,000.
The soccer festival is part of a 14-year-old event founded by director Terry Stefankiewicz and former IU coach Jerry Yeagley. The festival annually brings some of the nation's best teams together in August.
This year 18 of the 48 teams in the NCAA tourney field participated in the festival, with five making the final eight and Notre Dame winning it all.
“Each year the best of the best continue to view the Festival as the supreme place to complete against the finest teams in the country," Stefankiewicz said in a release. "They know they can count on being paired with another great team and Northeast Indiana always creates an electric atmosphere."
Added Mike Roeth, the Shindigz National Soccer Festival operations leader: “This may be unprecedented in NCAA sports where the prior (national) champions play against each other in the months before the next official season begins, in back to back years. It truly is very exciting.”
