Marcellus Young Casario, a defensive lineman prospect committed to Georgia, died Friday at age 18 after what his high school called a “sudden medical emergency,” ESPN’s Eli Lederman reported Saturday.
Rabun Gap-Nacoochee School, the boarding school Casario attended in northeast Georgia, confirmed the death of an unidentified student in a statement and postponed its football team’s semifinal playoff game against Cannon School on Friday.
“The boarding school had a medical incident this morning,” the school’s statement said Friday, according to Lederman. “Rabun Gap immediately followed our emergency response protocols, and local emergency personnel responded, transferring the student to the hospital.”
Casario, a senior at Rabun Gap, was considered a 3-star prospect according to the 247Sports composite rankings. He received offers from Michigan State, Georgia Tech, Miami and more before ultimately committing to Kirby Smart’s program in June.
Casario was originally from Halifax, Nova Scotia, and moved to Rabun Gap in 2025 in hopes of securing a college football scholarship.
“He was everything a coach wants in a player,” Rabun Gap-Nacoochee football coach Derek White said in a statement, according to Lederman. “(Marcellus) truly embodied our mission to ‘love one another.’ He was known for his relentless dedication, and his journey as a student-athlete was marked by hard work and true brotherhood with his teammates.”
