PEARLAND, TEXAS - The Shadow Creek High School football team will honor fallen player Chase Lightfoot by adding his "C.L." initials and number "65" to their helmets.
Lightfoot became very sick while playing in San Antonio Friday night. He later died at a hospital.
Members of the opposing team, St. Mary's Hall, have also asked to wear decals honoring Lightfoot, according to an Alvin ISD spokesperson.
An autopsy by the Bexar County Medical Examiner's Office determined that the 17-year-old died from a rare heart defect, but family says they are still waiting to get more information on what caused the tragedy.
Lightfoot's parents and younger brother held back tears as they answered questions from reporters while sitting next to their pastor at South Union Missionary Baptist Church. They say Chase was more than just a dedicated athlete. They say he was active in church, sang in the choir and often volunteered to help the needy and seniors.
Chase's mother says she has been overwhelmed by the support from his teammates and the community.
"This child knew everyone," Voronica Lightfoot said. "I had no idea he had so many friends. I am just in awe of the number of people he knew."
Lightfoot's friends set up a GoFundMe account and raised more than $25,000 within just a few days. The family hopes to use that money to help other Shadow Creek students.
"We are working to set up a scholarship to try to invest monies in things Chase took an interest in: feeding the homeless, working with the elderly and working with youth," Voronica Lightfoot said.
The death has been particularly hard on Chase's brother, Jordan, who is just a year younger.
"We created so many memories together," Jordan Lightfoot said. "He was my closest friend. He always had each other's back."
