The Athletics announced Saturday that Kurtz remains limited to participating in range-of-motion and strengthening exercises during his rehab for a right thumb capsule sprain, Martin Gallegos of MLB.com reports.
Kurtz was placed on the 10-day IL on July 11 due to the injury and will be without a clear timeline for a return until he's able to resume taking part in baseball activities. In the meantime, Tommy White, Jonah Heim and Jeff McNeil could all be candidates to pick up reps at first base in Kurtz's absence.
