Clarkson sustained an upper-body injury in the third period of Tuesday's game against the Capitals and will not return. Despite leaving with more than half of a period remaining, Clarkson gave fantasy owners exactly what they expected from him: a two-minute tripping penalty and a 10-minute misconduct penalty to bring his PIM total above the century mark for the season. The extent of his injury isn't immediately clear, but the Blue Jackets should provide a better assessment of his condition either after the game or following Wednesday's practice.
