In a statement, the James family said Bronny has a congenital heart defect which is treatable, according to medical professionals tasked with his care.
James, a top-20 recruit in the class of 2023, arrived at USC last month and is expected to suit up for the Trojans this season. He spent his high school career at Sierra Canyon High School (California), developing into a bona fide NBA prospect over the past couple of years. James was part of a highly touted recruiting class for USC coach Andy Enfield as one of four ESPN 100 prospects -- including Isaiah Collier, the No. 1 overall recruit in the 2023 class.
