The Detroit Pistons returned from the All-Star break Wednesday still uncertain when Reggie Jackson can begin practicing, let alone when he'll be cleared to play, but there are some encouraging signs. Jackson is entering the next stage of his rehabilitation this week following his Grade 3 right ankle sprain on Dec. 26. He has been cleared to begin light running and shooting, and to continue ankle strengthening exercises. The Pistons medical staff will monitor his progress this week in anticipation of beginning an escalation process toward resuming normal basketball activities. "He's doing a little bit more running, now he's running on full body weight, but he's not full speed yet," coach Stan Van Gundy said. "He's certainly not cutting. He's just starting the process here at eight weeks to get back. I don't know when it'll be." Van Gundy said there is nothing to indicate Jackson isn't healing properly. Jackson is encouraged. "I ran a little bit over the break and I came in and run today, had a great workout and I'm doing just a little bit more," Jackson said. "And then some of the stuff I've been doing just ramp it up a tad more." The Pistons were 19-14 when Jackson was injured in a game against Indiana. They are 9-15 without their starting point guard, who is averaging 14.6 points and 5.5 assists per game.
