Williams was rushed to an area hospital, but almost a week after his injuries, he was taken off a ventilator and died Friday, WAPT reported.
Sunday, the community came out to hold a candlelight vigil in Williams’ memory on the same football field where he was hurt.
To help pay for the week-long treatment, a GoFundMe account has been set up, WAPT reported.
Organizers wanted to raise $10,000 but nearly $49,000 has been donated over seven days.
"We know his family is going to have a mountain of medical bills," Errick Simmons, Greenville's Mayor, told WJTV. "He was on the ventilator for a week and he was in ICU."
The mayor also declared Thursday Jeremiah Williams Day. Three of the town's McDonald's restaurants will donate 20% of the sales that day to the family to help pay medical bills, WJTV reported.
