CHAMPAIGN, Ill. (AP) -- Tyler Griffey made an uncontested layup at the buzzer off a baseline inbounds pass and Illinois beat No. 1 Indiana 74-72 on Thursday night, the fifth straight week the nation's top-ranked team has lost.
The Illini (16-8, 3-7 Big Ten) trailed 41-29 at halftime and by double digits for most of the second half before closing the game on a 13-2 run over the final 3:36.
With the score tied, Indiana's Victor Oladipo turned the ball over and recovered to block a breakaway layup by D.J. Richardson out of bounds with less than a second to play.
Griffey, who was open after setting a screen, took the inbounds pass from Brandon Paul with .9 seconds left and gently laid the ball into the basket.
Hundreds of Illinois students rushed the court.
The upset ended a three-game losing streak for Illinois.
The Hoosiers (20-3, 8-2) took over the top spot in The Associated Press' Top 25 on Monday.
