• Robert Williams III
    C-F, Boston Celtics

    Brad Stevens said that Robert Williams wasn't feeling great after Thursday's light work and has re-started the league's concussion protocol from step one.

    It has also been reported that the big man was dealing with a headache today, which is not a great sign. Williams was riding a stationary bike at Thursday's practice and today he was spotted getting some treadmill work in. There's no set timeline for a return from a concussion, so fantasy managers will just have to hope for the best. Williams is going to be one of the league's top block specialists this season but isn't necessarily someone that must be drafted in standard-sized formats.
