Hancock was removed from Sunday's start against the Rays with an apparent hand injury, Shannon Drayer of SeattleSports.com reports.
The right-hander remained in the game after being struck in the hand by a comebacker during the opening frame, but he was lifted after issuing a two-out walk in the second inning. The specifics of the injury aren't yet clear, but for now the 27-year-old should be considered day-to-day.
