The Boston Celtics signed Kylor Kelley to an Exhibit 10 contract. Kelley's G League rights were recently acquired by the Maine Celtics, and he'll land there after the preseason.

Kelley went undrafted out of Oregon State at the 2020 NBA Draft. He's played in the G League, as well as in Canada and Germany. In 21 games for Raptors 905 last season, the 7-foot center averaged 7.5 points, 4.9 rebounds and 1.3 blocks in 15.3 minutes per game.
