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.
