The Red Sox should learn more about Rodriguez (ankle) next week after his walking boot is removed, Jason Mastrodonato of the Boston Herald reports.

Rodriguez has a history of lower-body injuries, from which his recovery has taken more time than initially expected. We'll learn more next week, but it's entirely possible a rehabilitation stint is in order for the left-hander. In the meantime, Brian Johnson will remain in the rotation, although the Red Sox have scouted starting pitching, including Toronto's J.A. Happ per Bob Elliott of CBC Sports.
