One NBA superstar is making progress toward a return from a knee injury, while another remains sidelined due to a knee problem.
Chicago Bulls guard Derrick Rose is engaging in full contact practices as he works his way back from left knee surgery. San Antonio Spurs center Tim Duncan, however, was due to miss a fourth consecutive game with a sore left knee.
Bulls coach Tom Thibodeau told reporters Wednesday that Rose, who underwent surgery on May 12 after he was injured in last season's playoffs, has no physical restrictions.
"He's full contact, yeah," Thibodeau said. "He can do all the cutting, he can do shooting, he can go off the dribble. So it's just a matter of him getting acclimated to playing in a game situation.
Bulls management has maintained that it doesn't want to rush Rose back. Rose's return is still targeted for after the Feb. 17 All-Star Game.
While Duncan remains unavailable for the Spurs, coach Gregg Popovich was expected to return to the bench Wednesday night when San Antonio plays host to the Charlotte Bobats, the San Antonio Express-News reported.
Popovich was sidelined for several games because of illness, but the Southwest Division-leading Spurs have maintained the NBA's best record at 36-11.
Spurs center DeJuan Blair (knee) also was expected to miss Wednesday's game.
--Dallas Mavericks center Chris Kaman is out indefinitely after suffering a concussion during a hard fall in practice Monday.
Kaman is dealing with headaches and dizziness as a result of the collision with teammates, the Fort Worth Star-Telegram reported.
He missed Tuesday night's 106-104 loss to the Portland Trail Blazers and could be out for all four games in the Mavericks' road trip.
Kaman is averaging 12.4 points and 6.2 rebounds per game this season.
--Former NBA center Greg Oden is hoping to return next season, and the Cleveland Cavaliers and Miami Heat appear to be the front-runners to land the 7-footer who last played in 2009.
Injuries have derailed the career of Oden, the former No. 1 overall draft pick who left Ohio State in 2007 after one season, since he entered the NBA.
Oden has undergone three microfracture surgeries on his knees, including two on the left knee. The last surgery was in February 2012.
Oden, 25, may meet with the Heat next week in Miami, CBSSports.com reported. The Cavaliers and several other teams are monitoring Oden's progress in rehab.
--The Cavaliers sent forward Kevin Jones to Canton of the NBA Development League.
Jones, a rookie from West Virginia, has played in six games for the Charge this season and averaged 23.8 points and 12.3 rebounds, posting five double-doubles. In 15 games with the Cavs this season, Jones is averaging 1.9 points and 1.5 rebounds.
--The Heat signed forward/center Chris Andersen to a second 10-day contract.
Anderson has seen action in one game with Miami since he signed his first 10-day contract on Jan. 10. He has two points and two rebounds in four minutes. The 10-year NBA veteran played in 32 games for Denver last season and averaged 5.3 points and 4.6 rebounds per game.
