Dexter Pittman has been assigned by the Miami Heat to the Sioux Falls Skyforce of the NBA Development League.

Pittman has appeared in four games with the Heat this season, totaling six points and seven rebounds in 12 minutes of action while shooting 3-of-5 from the field.

Pittman previously appeared in the D-League with Sioux Falls during the 2010-11 season appearing in 22 games (all starts) and averaged 14.5 points, 8.2 rebounds, 1.73 blocks and 1.2 assists in 27.7 minutes while shooting 53.6 percent from the field. 

Erik Spoelstra expects Pittman to stay in the D-League for an extended period.

The Boston Celtics will sign Jarvis Varnado of the NBA D-League's Sioux Falls on Monday, according to a league source.

The 6-foot-9 Varnado has averaged 14 points, 8.9 rebounds and 4.4 blocks with Sioux Falls.

Doc Rivers admitted on Sunday that the Celtics would look to sign a big man given the loss of Chris Wilcox, who could miss one month with a sprained ligament in his left thumb.

The Sioux Falls Skyforce have acquired center Hassan Whiteside. To make room for him on the roster the team waived forward Dan Coleman. The active roster now stands at 10 players.

Whiteside averaged 1.5 points and 2.1 rebounds in 19 games with the Sacramento Kings from 2010-12. He was selected in the second round (33rd overall) of the 2010 NBA Draft after playing just one season at Marshall University.

Jarvis Varnado of the Sioux Falls Skyforce was named NBA Development League Performer of the Week for games played Nov. 23 – Dec. 2

Varnado led Sioux Falls to a 3-0 record for the week, averaging 15.7 points to go along with 9.3 rebounds and a league-high 5.7 blocks.

Varnado has tallied 17 blocks through the opening three games of the season.
