Purdue Boilermakers running back Antonio Harris (22) runs the ball during the second half against the Southern Illinois Salukis at Ross-Ade Stadium.

The Big Ten opener between Southern California and Purdue took more than three hours to get started.

The first meeting between the Trojans and Boilermakers since 1998 was delayed due to lightning. It is taking place at Ross-Ade Stadium in West Lafayette, Indiana, and was scheduled to kick off at 3:40 p.m. ET.

However, teams were instructed to stay in their locker rooms and fans were instructed to seek shelter with heavy rains and thunderstorms in the area. Luckily, it did not storm for the entire evening and the weather should make it possible to get the full game in on Saturday, Sept. 13, according to AccuWeather.

College football lightning rules

NCAA rules state games must be delayed or must stop if lightning is detected within a six-mile radius of the stadium. Teams cannot return to the field until there is no lightning in the area for 30 uninterrupted minutes. The clock to resume plays resets with each lightning strike in the radius.

After there is no lightning in the area for 30 minutes, teams are then allowed a 10-minute warm-up before play can begin or resume.
