The Purdue football game against USC was delayed due to lightning in the area. The game, originally scheduled to start at 3:30 p.m. ET at Ross-Ade Stadium, was postponed because lightning was detected within a one-mile radius of the stadium. NCAA rules require a 30-minute delay after the last lightning strike before play can resume, and each new lightning strike resets this countdown, causing extended delays. Fans were directed to evacuate the stadium for safety, and the game was eventually rescheduled to start several hours later, at around 6:45 p.m. ET, due to continued weather concerns including heavy rain and hail. The delay lasted over three hours, with nearly 1.3 inches of rain recorded during that time.
