Bynum signed a two-year, $24 million deal with the Cavs in July. The teams holds a $12 million team option for the second season.
"I moved here a week after the press conference, I've been here ever since -- day in and day out just working,'' he said to the Cleveland Plain Dealer. "I'm there, focused. I'm doing everything I can do to get back. That's what all this is all about for me right now. I just want to play."
Cavaliers general manager Chris Grant said Bynum is doing everything he can to play this season.
"We've been very impressed with Andrew's work ethic and diligence in this process,'' Grant said. "He's doing everything possible to get back on the court as quickly as he can.''
Training camp starts Oct. 1 and Bynum says his rehabilitation is on schedule for his return.
"It's a fluid process,'' Bynum said. "I have no idea what the schedule's going to be for me. But I'm doing everything I can to be ready. I think with the program that has been made up, we have a good chance. "I'm optimistic I'm where I should be. Obviously, I want to be playing. But I'm taking baby steps, doing what the team and the doctors tell me. I'm doing my part. I come to work every day. I'm moving in the right direction.''
