The protest was set to take place Wednesday morning outside all Chicago public high schools.
CPS officials say they are making the cuts to deal with a budget deficit, but some parents say sports help teenagers become responsible adults and keep kids out of trouble.
"If we cut this program, where are these children going to go? They're going to go out onto the streets, into situations that we are desperately trying to keep them from being involved in," parent and CPS teacher Kelly Pfeiffer said.
Pfeiffer says kids also depend on sports to help them get into college and to earn scholarships.
