Anderson is dealing with a blister that may force him to miss Wednesday's start against the Royals, Laura Armstrong of The Toronto Star reports.

EDGE Analysis

Anderson played catch Saturday and said he was monitoring the hot spot, which remains a day-to-day issue. He developed the injury in Thursday's start vs. Minnesota, forcing him from the game after just 4.1 innings. With a 40-man roster at his disposal, manager John Gibbons has a slew of options available if Anderson become unavailable. As of now, the skipper hasn't expressed any concern with the southpaw's Wednesday availability.
