The Chicago Cubs have activated infielder Nico Hoerner for a rehab assignment, starting Sunday in South Bend, Indiana. Hoerner has been out since last June with a right oblique strain. The team plans to move Hoerner to Iowa when their Triple-A affiliate returns from its break. Hoerner’s injury is not considered major. The Cubs plan to have him move to Iowa once they move their Triple-A affiliate back to Omaha, Nebraska.
