Wilson was removed from Wednesday's game against the Giants with a left shoulder injury, Martin Gallegos of MLB.com reports.
Wilson's shoulder began to bother him after he made an awkward move to avoid a tag at home plate in the fifth inning, and the A's eventually made the call to take him out of the game in the ninth. The severity of his injury remains unknown, but the team could provide an update on his status ahead of Thursday's series finale.
