Although Curry said Monday that he needs at least that amount of time to be comfortable enough just to practice, New York's 6-foot-11 starting center also noted that the Knicks' doctors are convinced his knee hasn't become arthritic.
Curry said last week that he was close to being able to practice, but that target now appears to be mid-January.
"I think I'm close," Curry said following practice Monday, according to the New York Daily News. "I don't know. It all depends on how I feel. If I keep healing the way I am, I'm not too far away. I'm feeling better every day. I'm not quite where I want to be, but it's getting better."
The Daily News said Curry has been given three cortisone shots to his knee, but arthritis is not a concern.
"It's not that bad. The injections were to take the pain away. I'm getting better," Curry said, according to the paper.
Also excruciating for Curry: He's watched the Knicks (11-18) lose their past six games and fall into a share of last place with the Toronto Raptors (12-19) in the Atlantic Division.
"It's hard watching our team," Curry said. "I feel I can be the guy to get us over the hump and help us start winning games."
Last season, Curry averaged 13.2 points and 4.7 rebounds per game. During the preseason, he averaged 4.3 points and 2.5 rebounds in nearly 14 minutes.
