The Miami Heat have invited Jarvis Varnado, Justin Hamilton and Larry Drew II to the Sioux Falls Skyforce's training camp.

Varnado, Hamilton and Drew were cuts by the Heat in training camp.

All of those players are eligible to be claimed by any NBA team at any time, with the Heat not holding exclusive rights.

Guards Patrick Christopher and Kalin Lucas have reached deals to begin the season with the Chicago Bulls’ D-League affiliate, league sources told RealGM.

Christopher and Lucas had been released early in training camp with the Bulls this season, and the organization held their rights in order for both to play for the D-League’s Iowa Energy.

Christopher passed on several sizable offers from overseas teams.

Christopher, a 6-foot-5 two-guard, went undrafted in 2010 after averaging 15.6 points and 5.4 rebounds in his senior season at the University of California.

Lucas had a standout career at Michigan State, spending his first two professional seasons in Turkey and Greece.

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 – is 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.

Free agent guard B.J. Young – a recent release of the Rockets – will sign a deal with Houston’s D-League team, the Rio Grande Valley Vipers, a league source told RealGM.

Young was released by the Rockets early in training camp, but the former Arkansas standout received interest from the Los Angeles Lakers and Philadlephia 76ers before deciding to join the Rockets’ burgeoning pipeline of young talent, a league source said.

Daryl Morey has stockpiled several talented players to place into the Rockets’ developmental system, which will also include the recently waived Troy Daniels.

After averaging over 15 points and three assists in his sophomore season at the Unviersity of Arkansas, Young, 20, went undrafted in June’s NBA draft.

Young played for the Rockets in summer league, displaying moments of explosiveness averaging nearly 12 points on 51.6 percent shooting and two assists.

The San Antonio Spurs have released Myck Kabongo.

Sources say Kabongo is still expected to sign with the Austin Toros, the D-League affiliate of the Spurs.

Kabongo played collegiately at Texas in Austin.
