CHICAGO (CBS) — The football games at Rich Central and Rich South high schools will be missing a key element.

The student spectators.

In the wake of a brawl between students at both schools earlier this month, administrators at first made the decision to ban all fans–including adults–from the sophomore game at Rich Central and the freshman game at Rich South on Thursday afternoon and the varsity game, scheduled for 2 p.m. on Saturday at Rich South.

Both Thursday games were scheduled for 4:30 p.m.

An automated call from Mark Hopman, assistant principal for athletics and activities at Rich South, went out to parents on Thursday, notifying them of the decision.

Then, a second call went out to parents later in the afternoon stating that adults–but not students–would be allowed to attend.

On Oct. 1, a brawl broke out at Rich South High School when students from Rich Central arrived after being evacuated from their school by a bomb threat.

The bomb scare at Rich Central in Olympia Fields happened about 1 p.m., and prompted school officials to close the building and bus all students to Rich South in Richton Park.

As the buses arrived at Rich South, someone inside that school pulled a fire alarm, emptying the building, police and school officials said.

While students from both schools were waiting outside, a large brawl broke out among numerous students, which resulted in injuries to several people and several arrests
