HOUSTON — A buzzer malfunction caused a delay — a very loud, very unpleasant delay — of about 10 minutes in the first half of the NCAA Tournament’s South Region final between Iowa and Illinois on Saturday night.

When the buzzer sounded out of a media timeout with 7:43 left in the first half, it kept blaring uninterrupted for about seven minutes. Players stood on the court ready to play for a couple of minutes before both teams started to warm up as the buzzer continued to sound.

It was finally silenced, to cheers from the crowd, but then the main scoreboard and video screen that hangs over the middle of the court went dark.

The game ultimately resumed with the big scoreboard still off. Two smaller scoreboards at each end of the arena were working.
