UCLA sophomore forward Shareef O'Neal sat out the entire 2018-19 season after the school's medical team discovered an issue with his heart during a routine checkup in September.
Shareef - the eldest son of Hall of Famer Shaquille O'Neal - was diagnosed with a right anomalous coronary artery and underwent open-heart surgery in October. Had the abnormality gone undiagnosed, Shareef could've gone into sudden cardiac arrest.
"(It's) an artery that just grows in the wrong place," his mother, Shaunie, said on VH1's "Basketball Wives," according to ESPN. "He was born with it. He could've died from it. They let us know Shareef needed open-heart surgery. That made my heart break."
The condition isn't career-ending. Shareef returned to the court in late March and participated in his first team workouts in May. He's expected to return during UCLA's 2019-20 season.
Shareef was a four-star prospect coming out of high school, ranking 32nd in ESPN's class of 2018.
