A 6-foot-5 combo guard, Harper Jr. is the son of five-time NBA champion Ron Harper and older brother of San Antonio Spurs Kia All-Rookie First Team selection Dylan Harper. He went undrafted in 2022 out of Rutgers and played his first three seasons on Two-Way contracts with the Toronto Raptors and Detroit Pistons. In 2025, he signed a Two-Way contract with the Celtics, eventually earning a standard roster spot in April 2026.

Before signing his standard contract, he was averaging 24.3 points, 5.1 rebounds, 3.2 assists, 1.5 steals and 1.6 blocks on 45.5% shooting for Boston’s G League affiliate, the Maine Celtics.
