Thursday’s NCAA Tournament first-round game between No. 8 seed Louisville and No. 9 seed Creighton was delayed due to a Louisville fan throwing a full water bottle onto the court at Rupp Arena following a technical foul on Cardinals coach Pat Kelsey.

That delay came after Kelsey worked up a heated conversation along the sidelines with one of the officials, resulting in him being assessed a technical foul in a then-73-61 deficit to the Bluejays.

At the 4:40 mark of the second half, a fan from behind the Creighton bench threw a bottle of water onto the court after Kelsey was assessed a technical.

“That was a full bottle of water. That was very dangerous. Right over the Creighton bench. I tell you, whoever did that, should never be allowed to come into this arena again,” CBS broadcast Brian Anderson said on the broadcast alongside Jim Jackson.

Jackson said on the CBS broadcast that police at Rupp Arena headed to the section where the fan was sitting to handle the situation.

“It’s unnecessary. So you get upset about a call, so what?” Jackson said. “You don’t do that.”

Kelsey’s technical foul led to a four-point play by Creighton to extend its lead to 77-61, as Steven Ashworth successfully hit two free throws at the line and Jamiya Neal hit a jumper.

The winner of Thursday’s first-round game will advance to the second round of the NCAA Tournament on Saturday, March 22 against the winner of No. 1 seed Auburn vs. No. 16 seed Alabama State, which follows the conclusion of the Bluejays-Cardinals game.
