He feels stronger and believes his jumper has improved. But as far as when Derrick Rose unveils such developments, well, that's a deep, not to mention undefined, answer.

"It can be tomorrow where I feel I can play next game," Rose said after Thursday's morning shootaround. "Nobody knows but God."

Speaking to a group of reporters in Chicago for the first time since last October, Rose reiterated he has suffered no setbacks in the 10 months and nine days since doctors surgically repaired the torn anterior cruciate ligament in his left knee.

But with just 15 games remaining following the Bulls' game Thursday night with the Trail Blazers, Rose also reiterated caution for the rehab process, which has included expected pain as his activity level has increased.

"Still about the same where you warm up a little bit, be loose, then activity picks up and it gets back sore," Rose said. "It's going through that. I'm just getting used to my activity picked up a little bit. Just getting used to running, playing 5-on-5, doing everything I used to do."

Doctors medically cleared Rose for full-court scrimmaging on Feb. 18. Last May, team physician Brian Cole, who performed the surgery, said playing in games would be the final phase of Rose's rehabilitation.

As of now, Rose acknowledged the mental component and severity of the injury are keeping him sidelined.

"Bad," Rose said, when asked how much he wants to play. "But … my health is the biggest key. I'm only 24 years old. I have the whole future in front of me. I'm just trying to take my time.
