The Athletics placed Kuroda-Grauer on the 10-day injured list Tuesday following surgery for a ruptured testicle.
The A's haven't provided a timeline for Kuroda-Grauer's return, though he will likely remain on the shelf beyond the 10-day minimum. Max Muncy will come up from Triple-A Las Vegas in a corresponding move and could see time at third base while Kuroda-Grauer is out.
