Celtics Sign Ron Harper Jr. to Two-Way Contract, Filling Roster Spot

The Boston Celtics have reportedly signed forward Ron Harper Jr. to a two-way contract, filling their open roster spot after waiving guard RJ Luis Jr. on Wednesday. Harper, the son of former NBA player Ron Harper and older brother of San Antonio Spurs rookie Dylan Harper, is in his second stint with Boston, having signed in July 2024 and spent the first half of the 2024-25 season with the Maine Celtics in the G League. The 25-year-old appeared in three of Boston’s four preseason games this year, averaging 4.3 points over 10.6 minutes, hitting 42.9 percent of his 3-pointers, and playing solid defense. He joins Amari Williams and Max Shulga, completing Boston's three two-way slots. With two-way players limited to 50 games with the parent club, Harper is expected to see significant time in Maine, providing extra wing depth for the Jayson Tatum-less Celtics.
