The Dodgers placed Muncy (hamstring) on the 10-day injured list Friday.
Muncy will miss at least a week after suffering a hamstring strain during last Sunday's game versus the Phillies. The Dodgers called up Michael Busch from Triple-A Oklahoma City to take Muncy's spot on the 26-man active roster, but Chris Taylor may get the first crack at replacing Muncy as Los Angeles' everyday third baseman.
