McCullers (forearm) was transferred to the 60-day injured list Monday, Chandler Rome of the Houston Chronicle reports.
McCullers is still working his way back from the forearm injury he suffered during the postseason. He started throwing last week but remains without a clear timeline, though his move to the 60-day injured list at least clarifies that he won't return before early June. The transaction clears a spot for Yordan Alvarez to return from the COVID-19 injured list.
