Andrew Bynum said today that he hopes to be back on the practice court in another week or two. If that goes well, he plans to rejoin the Lakers’ active roster after a week of workouts with his teammates. And that means the 7-foot center would have a chance to play in a handful of games before the playoffs start next month. The Lakers’ final regular-season game is April 14. Bynum has been sidelined by a torn right knee ligament since Jan. 31.
