The Dodgers placed Smith on the 10-day injured list Thursday, retroactive to Monday, due to neck inflammation.
Smith has missed the Dodgers' last four games because of his injured neck, and manager Dave Roberts confirmed Wednesday that the All-Star backstop would require an IL stint and ramp-up period before returning to action. Dalton Rushing will fill in behind the plate most days while Smith is out, and Chuckie Robinson will join the big club from Triple-A to work as the backup catcher.
