Ron Harper Jr. (guard/forward)
Ron Harper Jr. has signed an Exhibit 10 contract for the second season with the Celtics, as first reported by Michael Scotto of HoopsHype.
Harper Jr, the older brother of No. 2 pick Dylan Harper, played at Rutgers for four seasons and went undrafted in 2022. He averaged 12.6 points on 43.9% shooting in college. The 25-year-old is a versatile scorer who can create his own offense, while also being a catch-and-shoot threat.
Harper was on the Celtics 2024 Summer League team and on the Maine Celtics last year. He left Maine in January after being offered a two-way contract by the Detroit Pistons, but was waived by the Pistons in July. He rejoins the Celtics organization this fall.
Jalen Bridges (forward)
Jalen Bridges was a member of the Celtics Summer League team in 2025, appearing in 4 games and averaging 8 points on 44.4% shooting and 3 rebounds.
The 24-year-old went undrafted in the 2024 NBA Draft after a collegiate career that included two seasons at West Virginia and two seasons at Baylor. Bridges was a strong defender in college who seems slated to be a 3&D player in the NBA. He can move well without the ball and is a good cutter.
After going undrafted, he signed a two-way contract with the Phoenix Suns....
Now, he gets another opportunity in Boston.
Kendall Brown (forward/guard)
Kendall Brown was a member of the Celtics Summer League team in 2025, appearing in 5 games. He averaged 8.6 points, 1.8 rebounds, and 1 assist per game, and shot 69.2% from the floor.
“I saw consistent energy — he’s a guy that knows his role,” Summer League head coach Matt Reynolds said. “For the most part, he’s elevated our team. Every time he’s been in the game, he’s been pretty high energy. He’s almost guaranteed to get one or two transition baskets — pretty savvy defensive player, active.”
Aaron Scott (guard)
Aaron Scott was a member of the Celtics Summer League team in 2025, appearing in 2 games. In the last Summer League game, he tallied 9 rebounds (7 offensive), 3 assists, a steal, and a block in 18 minutes off the bench.
“That’s exactly the type of player he is,” Reynolds said of Scott’s rebounding. “It’s not the easiest thing to do — to sit for essentially four games, come in and just be a relentless crasher.”
Scott went undrafted this past season after a standout year at St. John’s that saw him average 8.4 points and 4.3 rebounds per game. Prior to that season, he spent three years at North Texas.
The 6’6 wing is looking to carve out a 3&D role in the NBA.
Hayden Gray (guard)
Hayden Gray was also a member of the Celtics 2025 Summer League team, averaging 3.5 points on 75% shooting in 11 minutes across two games. As first reported by CelticsBlog, he signed with the Maine Celtics shortly after
Gray was the NCAA’s leader in steals last year, averaging 11.2 points, 3.3 assists, and 3.1 steals at UC San Diego. While his biggest strength is on the defensive side of the ball, Gray shot 41.8% from three-point range last season.
Hason Ward (forward)
Hason Ward is another returner from last year’s Maine Celtics roster (who was also with the Boston Celtics for training camp). Last year, the 24-year-old averaged 8.4 points, 7 rebounds, and 1.9 blocks per game in 34 games with the Maine Celtics. Ward, who has a 7’4 wingspan, was one of the best shotblockers in the G League.
This past summer, Ward was a member of the Oklahoma City Thunder’s 2025 Summer League, appearing in 4 games and averaging 5 points and 2 rebounds in 11.8 minutes per night.
Before going undrafted in 2024, Ward spent three seasons at VCU and two at Iowa State. He averaged 5.1 points, 3.7 rebounds, and 1.2 blocks per game in his five-year NCAA career.
