D-League forward James Nunnally will sign a 10-day contract with the Philadelphia 76ers on Sunday, league sources told RealGM.

Nunnally, who has averaged 18.1 points and 4.5 rebounds with the Bakersfield Jam and Texas Legends this season, worked out for the 76ers on Tuesday.

A 6-foot-7 wing shooter, Nunnally earned two 10-day contracts with the Atlanta Hawks in January. He scored 18 points and grabbed eight rebounds in 54 minutes of action with the Hawks.

Nunnally played four collegiate seasons at UC Santa Barbara.

The 76ers are 15-51, losers of 20 consecutive games, and have intended to use their 15th roster spot as a tryout opportunity for young players.

The Charlotte Bobcats will work out Ike Diogu, Mickell Gladness and Denzel Bowles on Thursday afternoon for a potential 10-day contract, league sources told RealGM.

Diogu and Gladness fit in the mold of frontcourt players with previous NBA experience, able to provide Charlotte with a veteran presence heading into a most likely postseason berth.

Even so, the Bobcats view Bowles – a 6-foot-10 center who averaged 26 points and nine rebounds in the Chinese Basketball Association this season – as a talented project. Bowles also has received interest from the Miami Heat, a league source told RealGM.

The first 10-day contract of Justin Hamilton will expire on Thursday, but he remains intriguing to the Bobcats, who have been without Brendan Haywood all season due to stress fracture in his left foot.

Diogu, a six-year NBA veteran most recently with the San Antonio Spurs in 2011-12, has averaged 16.7 points and 9.3 rebounds with the Bakersfield Jam of the D-League this season.

Gladness has averaged 8.4 points and 6.9 rebounds for the D-League’s Reno Bighorns. He played 26 games with the Miami Heat and Golden State Warriors two seasons ago.

Karron Johnson has signed a contract with the D-League, a source tells RealGM.

Johnson left his Polish team, Kotwica Kolobrzeg, last week. Johnson was averaging 11.7 points, 4.9 rebounds and 1.2 assists in 21.1 minutes per game in 15 appearances.

Johnson played collegiately at Shaw.

The Erie Bayhawks have released Chris Smith.

Smith began the season with the New York Knicks under controversial circumstances as the younger brother of J.R. Smith.

Prior to his release, a source says that Smith had already left the team due to having issue with his playing time.
