Fans are calling foul against Northern Iowa and its business sponsor after a student was denied a $10,000 prize in a halftime basketball shooting promotion.

The flap began Wednesday night, when Northern Iowa student Dalton Hinsch got the chance at the prize if he made a layup, a free throw, a three-pointer and a half-court shot within what he and the crowd thought was a 30-second time frame.

Hinsch made all four shots within 27 seconds, sending the crowd into a frenzy. Officials then declared Hinsch hadn’t got the last shot off in time.

The UNI Athletic Department says the promotion’s insurer required all four shots to be made in 24 seconds.
