An MRI showed Andrew Bynum's knees are improving and he has been cleared to step up his rehab, but there is still no timetable on his return. Sixers GM Tony DiLeo called it good news but admitted he doesn't know if Bynum can help the team this season. According to DiLeo, increased activity is part one of a six-step rehab process. The team will wait to see how his knee responds to the added stress before determining anything further. The Sixers big man did say he's "confident" he'll suit up this year, but it appears we've still got a ways to go before that happens.
