Andrew Bynum received Synvisc injections in both knees on Thursday, part of a scheduled step in his rehab. Bynum can resume work on Sunday, and although there is no timetable for his return, the prevailing hope is that he will be able to play as early as February 20 after the All-Star break. Bynum is worth an add if he's still floating around on your waiver wire, but owners have to be prepared to gamble on his health.
