Andrew Bynum's agent, David Lee, said Tuesday that the 76ers center would have his knees examined again on Dec. 20.
Bynum has not played this season for the Sixers as he recovers from bone bruises to each knee and weakened cartilage. He will have a battery of tests conducted, Lee said. The agent added that the swelling in Bynum's knees had gone down.
Bynum's personal physician, David W. Altchek, will conduct the examination in New York.
The Sixers' bench was again without the services of swingman Nick Young because of a hyperextended left big toe.
Young missed his first game of the season Saturday in Chicago with the same injury. Young said he hopes to be able to play by Friday, when the Sixers play the first of two back-to-back games against Boston.
Young, averaging 9.6 points per game, is the Sixers' leading scorer off the bench.
Sixers coach Doug Collins and associate head coach Michael Curry talked recently about trying to find more playing time for rookie forward Arnett Moultrie. Those minutes are likely to come with the Sioux Falls Skyforce of the NBA Development League.
Moultrie was the 27th overall pick in the draft. Before Tuesday's game against Minnesota, he had appeared in just five games, averaging less than one point and 1.2 rebounds.
"It's hard to get him minutes," Collins said. "There are some spots on the schedule where maybe he can be gone for maybe 10 or 11 days and get maybe six or seven games in, but he needs to play and get in shape."
Moultrie missed about four months of conditioning during the summer after suffering a sprained left ankle that was slow to heal.
"I really didn't think he would be ready to make a contribution until January," Collins said.
