University of Buffalo redshirt sophomore defensive end Solomon Jackson died Monday, one week after he collapsed during offseason training.
He was transported to an area hospital for what the school called "a medical emergency" on Feb. 22. He died on Monday, the University of Buffalo announced.
Solomon, from Stone Mountain, Ga., was known as "Solo," around the team.
"It is with deep sadness that I write to share that we have lost one of our own, UB football player Solomon Jackson, who passed away last night," UB Athletics Director C. Allen Greene said in a statement Tuesday morning. "Our heartfelt condolences and deepest sympathies go out to Solomon's family as together we mourn his tragic and untimely death.
"From the outpouring of prayers and support over the past week since Solomon was hospitalized, it has been abundantly clear just how many lives he touched on a daily basis through his contributions and character: as an athlete, as a student, as a friend and mentor to others, and as an active and engaged member of our campus community."
