A “brilliant” Long Island heart surgeon died from a traumatic brain injury days after he was slugged on a Brooklyn street during a road rage incident.

Jaime Yun, 56, was also a beloved father of two, WCBS reported.

Police said that Dexter Alexander, 31, punched Yun in the face, knocking him to the ground, during the June 8 incident.  Yun was hospitalized, initially in stable condition with a head injury, but that condition worsened, and he died on June 16, police said.

Alexander was arrested last week and charged with assault, police said. It’s unclear if charges will be upgraded.

Details on the road rage incident, which happened near his hospital, were not made available.

According to an obituary, Yun was born in Venezuela and later moved with his family to Colombia. The family emigrated to the United States in the 1970s, and Yun earned degrees from  Columbia University and the New York University Medical school.

He is survived by his wife, Tyan; his children Christopher and Lauren; his five brothers, Alfonso, Julio, Enrique, Fernando and Jairo, their wives and several nieces and nephews.
