Jeremy Nelson collapsed during the game at around 10:20 p.m., according to his coach Bryan Larrieu.
"He was having a heck of a game when he pulled up from missing a shot," Larrieu told the Atlanta Journal Constitution. "We pulled him out to get some rest, eight seconds later, he was in and out of consciousness."
Nelson was rushed to Gwinnett Medical Center where he later died, according to Larrieu. He had no information on the cause of death.
"He was a phenomenal kid, with a great sense of humor, a loving kid," said Larrieu, who had coached the 6-foot player for four years.
Jeremy was well thought of at Buford Middle School, said schools superintendent Dr. Geye S. Hamby on Sunday.
"Jeremy was a very kind young man and an excellent student athlete. Jeremy had a presence in the hallways and on the court. He was a young man that always shared kindness with others and one that the students enjoyed being around. His very pleasant demeanor will be missed by all."
Jeremy's twin sister, Jessica, also plays basketball for Buford's seventh-grade team. His older sister Kristina, a senior on the Buford high school team recently signed to play with Notre Dame.
"He was just a wonderful kid, said DeMarcus Irons, who coached Jeremy when he was 10, and has known him since he was 8 years old. "It's a big loss. He represented everything good we were trying to do with these kids," in the league.
