A profane chant by Indiana’s student section has drawn the ire of IU athletic director Fred Glass.

Glass emailed student season ticket holders on Wednesday, reprimanding those that shouted profanity at Purdue center Matt Haarms during Tuesday night’s game at Simon Skjodt Assembly Hall.

On at least two occasions during the contest, students chanted “(Expletive) you, Haarms!” after the Boilermakers’ 7-foot-3 center tangled with IU’s De’Ron Davis during a physical head-to-head matchup in the post. Haarms also riled the Indiana crowd when he inadvertently tripped Romeo Langford during a fastbreak, drawing a foul on the play late in the first half.

Haarms, who delivered the game-winning basket on a tip-in with 3.2 seconds remaining in Purdue’s 48-46 win, finished with four fouls — including a technical earned during one of his run-ins with Davis.

A day later, Glass sent a three-paragraph note to IU’s students, requesting better behavior during future games.

Glass’ letter is below:
