With the Boston Celtics as the leading candidate to acquire his rights, Romero Osby is finalizing a deal to sign in the NBA D-League, league sources told RealGM.

Osby was a final cut of the Orlando Magic, who selected the rugged, active forward with the No. 51 pick in the NBA draft. Since Osby’s release in training camp, the Oklahoma City Thunder, Golden State Warriors, San Antonio Spurs and Brooklyn Nets have also expressed interest in him, sources said.

Fort Wayne currently owns rights to Osby, but the Celtics’ D-League affiliate – the Maine Red Claws – are working to acquire the 23-year-old. The Celtics have one roster spot open and could call up Osby at a point that is flexible on the team’s salary situation.

Osby averaged 16 points and seven rebounds last season at the University of Oklahoma. He was part of the Magic’s summer league team and became one of the last rookie signings to officially join his drafted organization.

In seven preseason games for the Magic, Osby averaged 5.7 points and four rebounds in 15.4 minutes a game.
