"There is not a specific date but in February," Bynum said. "That's the target, in February, I guess."
Bynum went to New York on Thursday to receive injections of Synvisc-One, a lubricant that is used to treat osteoarthritis. He receives the injections twice a year.
Richardson's knee
Sixers guard Jason Richardson missed his sixth game Monday with synovitis (inflammation) in his left knee.
"He's getting a third opinion on his knee so he's probably going to be out for a while," Sixers coach Doug Collins said.
Collins probably will continue to start Nick Young at shooting guard until Richardson, averaging 10.5 points per game, is ready to return.
Vucevic's growth
Collins said that extended playing time is helping Orlando center Nik Vucevic to develop.
Vucevic entered Monday's game against his former team, the Sixers, averaging 12.1 points and a team-high 11.3 rebounds through 47 games. "He's playing the same way," Collins said. "He's just getting 32 minutes a night."
Last season as a rookie, Vucevic averaged 5.5 points and 4.8 rebounds in just under 16 minutes per game. The Sixers traded Vucevic and last year's first-round pick, Maurice Harkless, in the Bynum deal. Harkless started against the Sixers on Monday.
Vucevic said he understood the trade."I didn't take it personally," he said. "I just used it as motivation to get better and prove myself. I wish I had played. But the plan is eventually get to the playoffs. I will get more chances."
In the house
Actor and Philadelphia native Will Smith, a Sixers minority owner, attended the game on Monday.
