As NBA transactions begin to formalize this week, a promising young guard has re-signed with the Boston Celtics in an official capacity. Ron Harper Jr. is staying within the Celtics organization, per Michael Scotto of HoopsHype, who reports that the deal is four years long and worth a total of $13.7 million. The NBA transaction log confirms the signing as officially completed. The Celtics had previously declined a team option on Harper Jr. before moving forward with this new contract as they recalibrate their salary structure.
During the 2025-26 season, Harper Jr. appeared in 29 games for Boston, averaging 4.0 points and 1.7 rebounds in 11.0 minutes per game while shooting 35.0% from three-point range. In the G League, he starred for the Maine Celtics, posting an impressive 25.4 points per game on 38.7% three-point accuracy, along with 5.1 rebounds, 3.6 assists, 1.3 steals, and 1.3 blocks per game.
For context in the broader family tale, Harper Jr.’s father is the legendary Ron Harper, a five-time NBA champion who earned titles with the Chicago Bulls and Los Angeles Lakers. The elder Harper’s career spanned 15 seasons and 1,009 NBA games, with a production average of 13.8 points per game over his tenure.
Ron Harper Jr. isn’t the only Hoops name in the family. His other son, Dylan Harper, just wrapped a standout rookie season with the San Antonio Spurs. While Dylan has a head start in terms of NBA production and potential, both brothers possess considerable talent and upside on the basketball court.
