Georgia football commit Marcellus Young Casario, a three-star defensive lineman from Canada, died on Friday following an incident his high school described as "a sudden medical emergency."
Casario was a senior at Rabun Gap-Nacoochee School, a boarding school located in northeast Georgia. In a statement Friday afternoon, the school confirmed the death of an unidentified student and later postponed its football program's state semifinal playoff game against Cannon School on Friday night. A post on Rabun Gap's official social media accounts Saturday afternoon confirmed the 18-year-old student as Casario. No other details have been released at this time.
"The boarding student had a medical incident this morning," the statement from the school read on Friday. "Rabun Gap immediately followed our emergency response protocols, and local emergency personnel responded, transferring the student to the hospital."
Casario began his football career at St. Andrew's College, an independent boarding school in Aurora, Ontario. He transferred to Rabun Gap-Nacoochee prior to his junior season in 2025 in pursuit of a college football scholarship. The 6-foot-5, 255-pound defender took official visits to Georgia, Georgia Tech and Michigan State in the spring and held offers from Miami and Virginia Tech, among others, when he committed to the Bulldogs earlier this year on June 15.
"He was everything a coach wants in a player," Rabun Gap-Nacoochee football coach Derek White said in a statement. "[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."
Per ESPN rankings, Casario was the nation's 49th-ranked defensive end and Georgia's No. 13 overall pledge in coach Kirby Smart's 2027 recruiting class.
