The NFL linebacker who overcame a life-threatening heart condition
In short: Before becoming an elite defender for the Denver Broncos, Jonathon Cooper faced a series of severe medical hurdles that nearly derailed his career. From being born nine weeks premature to undergoing three major heart procedures just days before the NFL draft, his journey is one of extreme physical resilience.
Jonathon Cooper's path to professional football was marked by early adversity. Born in Gahanna, Ohio, he arrived nine weeks prematurely weighing only 4 pounds. His mother, Jessica Moorman, initially planned to put him up for adoption but chose to raise him herself after his two-month stay in an intensive care unit.
His athletic development began at age six, fueled by a workout circuit created in his parents' basement. Nevertheless, while attending his first year of secondary school, he received a diagnosis of Wolff–Parkinson–White syndrome, an uncommon cardiac disorder marked by excessive heart rates. This health struggle intensified just two days before the 2021 NFL draft when doctors discovered atrial fibrillation, requiring three separate procedures to stabilize his heart rhythm.
Despite these complications, Cooper's leadership and 'motor' earned him a selection by the Denver Broncos in the seventh round (239th overall). He signed his rookie contract on June 15, 2021. His professional career saw significant growth; he led the Broncos in sacks during the 2023 season with 8.5 and reached a double-digit milestone of 10.5 total sacks by the end of 2024.
Cooper's trajectory has remained complex, involving both high-level achievement and legal scrutiny. Following his success on the field—including being named AFC Defensive Player of the Week in March 2025—he faced domestic violence charges in June 2026. These incidents led to him being placed on the commissioner's exempt list on August 30, 2026, highlighting the volatile intersection of professional success and personal conduct.
