Cardinals' Jordan Walker: Needs rehab assignment

Walker (appendix) is rejoining the team this week in Pittsburgh to meet with the training staff before heading out on a rehab assignment, Derrick Goold of the St. Louis Post-Dispatch reports.

The 23-year-old has apparently recovered well from appendicitis, but he won't return from the 10-day injured list when first eligible Friday. Walker may need only a couple rehab games in the minors and could be back with the Cardinals early next week.
