"The 'illness' that's causing the postponement of tonight's show is me," Reznor wrote in a message posted at NIN's official website later in the day. "I'm the sickest I've felt in a long time and there's no way I could've pulled off a show tonight. Please know I hate to do this, sorry for the inconvenience."

A March 10 make-up date has been set, and tickets for tonight's show will be honored for the rescheduled performance, according to organizers.

NIN has been on the road since last spring in support of its May 2005 release, "With Teeth," which features the singles "Only," "Every Day Is Exactly the Same" and "Hand That Feeds." The latter track was nominated for a Grammy in this year's Best Hard Rock Performance category, the trophy for which went to System of a Down for its song "B.Y.O.B."
"With Teeth"--NIN's first new studio set since 1999's "The Fragile"--debuted at No. 1 on The Billboard 200 chart.
