If the Trail Blazers have put the brakes on Brandon Roy's ambitious attempt to return on this three-game trip, it's safe to say the team has left the return of Marcus Camby idling in neutral.

Camby, in his first interview since resuming practice, said Thursday that he will not play today when the Blazers visit the Toronto Raptors. But after that ... well, nothing has been ruled out.

"It's all predicated on how I feel," Camby said after the Blazers went through a light workout at Air Canada Centre on Thursday night. "I really can't give you a definitive answer right now. I just got on the court yesterday for 30 minutes. I've got to crawl before I can walk."

Officially, Camby listed himself as doubtful for the Blazers' final two games on this trip -- Sunday at Detroit and Monday at Minnesota -- but offered a carrot of hope, proclaiming, "Anything's possible."

Coach Nate McMillan, echoing his words from Wednesday, said the Blazers are not putting a timetable on the return of Camby or Roy and remain committed to bringing the players back slowly.

Camby underwent arthroscopic surgery on his left knee Jan. 20 and, at the time of his procedure, the Blazers said his rehabilitation would last three weeks -- a time frame that passed Thursday. He returned to practice Wednesday and went through a 30-minute workout that included some four-on-four halfcourt scrimmaging.

The Blazers' starting center said he put himself through a wide range of activities during the limited workout, including some "banging" in the post. Camby acknowledged that he experienced some "discomfort" in his left knee, but dismissed it as a normal part of rehabilitation. Overall, Camby said, he left encouraged by his progress.

"It felt good for the most part," he said. "It's all about getting my timing down, getting my strength back in my knee and just feeling more comfortable out there on the basketball court. It was a big step and I'm just going to build from there."
