The Celtics suffered another great loss in 1993 when Lewis went into sudden cardiac death on the basketball court during a summer practice and passed away at just 27 years of age. He had a history of heart problems and was diagnosed with hypertrophic cardiomyopathy, a heart defect.

During his brief career, Lewis showed flashes of turning the Celtics around, averaging 20.8 points per game in his last two seasons. Years later, he'd have his #35 jersey retired at the Garden.
