Indiana's weekend loss was Duke's gain in the college basketball polls.
The Blue Devils moved up one spot to No. 1 in the Associated Press men's basketball Top 25 on Monday after Indiana lost in overtime to in-state rival Butler 88-86 on Saturday in Indianapolis.
Duke (9-0) received 62 of 65 first-place votes. The Blue Devils were idle last week.
The last time Duke topped the AP poll was during the 2010-11 season. Overall, the Blue Devils have held the No. 1 spot for 123 weeks, 11 behind UCLA for the most in history.
Michigan (11-0) moved up to second and was followed by Syracuse, Arizona, Louisville, Indiana, Ohio State, Florida, Kansas and Illinois.
The Hoosiers (9-1) had been No. 1 since the preseason. Butler (8-2) appeared in the poll for the first time since the 2010-11 season at No. 19 after the upset win.
