CBS News reports Schemm, a senior linebacker at Wallace County High School, was pulled off life support Wednesday afternoon, according to Swedish Medical Center in Denver.

Schemm’s father, David Schemm, told CBS affiliate KWCH in Wichita, Kan. that his son suffered brain trauma after the game, which caused it to swell and cut off blood flow. Schemm collapsed on the sidelines after scoring a touchdown. He was taken by ambulance to a local hospital before being flown to Denver, about 220 miles east of Sharon Springs.

A hospital spokesperson told the Associated Press that Schemm had been declared brain dead earlier Wednesday, but was kept on life support for friends and family to “pay their respects.”
