Harrison (elbow) said a precautionary MRI returned "all good" and that he had no issues during his bullpen session Saturday, Adam McCalvy of MLB.com reports.
The left-hander landed on the shelf July 8 due to elbow soreness, but he appears to have avoided a serious injury and quickly returned to mound work. Harrison will be eligible to come off the injured list Friday, though he may need to face live batters before rejoining Milwaukee's rotation.
