AYSO Regional Commissioner Philip Cordero said all of the league's equipment, including goals and nets, were stolen last weekend. The equipment was stored in a trailer at Quail Valley Middle School in Phelan.
It will take $8,000 to $10,000 to replace the equipment.
The AYSO Region 538 soccer league is non-profit and serves some 700 kids from eight schools in the San Bernardino County community near Wrightwood.
"It puts our program in jeopardy," Cordero said. "Without this equipment, we cannot provide a program for our community."
For many kids in the remote community, soccer is everything.
"We all come here on Saturdays and we look forward to it," said soccer player Brandon Barber.
"Please bring back the goals, we're really sad you took them," said Rachel Gnuse, a soccer player.
Anyone with information is asked to contact the San Bernardino County Sheriff's Department at (760) 245-4211.
Anyone wishing to help replace the stolen equipment can contact Commission Philip Cordero at (661)478-2421 or firstname.lastname@example.org.
