20-year-old college football player dies from head injuries sustained during game

Burnett was 20 years old. 

"Medrick was more than an exceptional athlete; he was a remarkable young man whose positive energy, leadership and compassion left an indelible mark on everyone who knew him," Bryant said in a statement, according to TMZ Sports. 

"While words cannot adequately express our grief, we are humbled by the strength of his family, who stood by his side throughout this unimaginable ordeal."

Dominece James, Burnett's sister, had a GoFundMe established for her younger brother, explaining he had brain bleeds and swelling from the injury. 

"He had to have a tube to drain to relieve the pressure, and after 2 days of severe pressure, we had to opt for a craniotomy, which was the last resort to help try to save his life," James said on the GoFundMe page.

Burnett was a 6-foot-2, 225-pound linebacker who grew up in Lakewood, California. 

He played in five games this season, registering five tackles.
