Boston Celtics

On Tuesday, the Boston Celtics announced the signing of rookies Justin Bibbs, Nick King, and Jeff Roberson, moves that finalized the team’s 20-player Training Camp roster.

The 22-year-old Bibbs joins the Celtics training camp roster after averaging 5.0 points, 1.7 rebounds and 1.0 assist in six games (three starts) with Boston’s 2018 Las Vegas Summer League team. The 6-foot-5 Bibbs spent his collegiate career with Virginia Tech.

King, meanwhile, was the reigning Conference USA Player of the Year, and averaged 21.0 points, 8.4 rebounds and 2.0 assists in 33 games (all starts) during his lone season at Middle Tennessee State. The small forward spent the summer with the Los Angeles Lakers.

And the 22-year-old Roberson’s arrival to the C’s comes after having spent four years with Vanderbilt, and having spent the summer with the Golden State Warriors organization.

The roster features 13 returning players from a season ago, and is obviously headlined by the return of a healthy Kyrie Irving (knee) and Gordon Hayward (ankle/leg) to the team’s starting five.

And it’s worth noting that second-year pro Jabari Bird, arrested earlier this month for a domestic violence incident, is listed on the Celtics’ training camp roster, but will not be with the team.

The Boston Celtics complete training camp roster.

The C’s first preseason game will be on Sept. 28 against the Charlotte Hornets at the Dean E. Smith Center. Their first home preseason game is set for Sept. 30 against the Hornets at TD Garden.
