The Boston Celtics have reached a three-year, $9 million agreement with forward Ron Harper Jr., according to ESPN's Shams Charania.
The contract marks the 26-year-old's first fully guaranteed NBA deal.
To finalize the long-term contract, the Celtics will decline Harper's $2.6 million team option for the upcoming offseason.
The 6-foot-5 wing previously played on an Exhibit-10 contract with Boston before earning a standard roster spot in April.
Harper's journey to a guaranteed deal included stints with the Toronto Raptors and Detroit Pistons.
He spent time with the Maine Celtics and on a two-way contract with Detroit before returning to Boston, where he averaged 4.2 points and 1.7 rebounds over 29 games.
His standout performances included a 27-point game against the Orlando Magic and an 11-point outing in Houston while defending Kevin Durant.
After recovering from a season-ending shoulder injury, Harper participated in the 2024 Summer League and expressed his readiness for a larger role.
"I'm a player that's going to play hard, play the right way, play within himself," Harper said.
He added, "I feel like I know the system; the coverages are like the back of my hand."
The signing comes amid ongoing trade discussions involving Jaylen Brown. Other Celtics players eligible for extensions this offseason include Jordan Walsh, Neemias Queta, and Payton Pritchard.
