Marlins losing Yelich to DL?

On Friday night, Miami Marlins left fielder Christian Yelich "exited the game after the first inning with back spasms" and the team initially called the outfielder day-to-day with a lower back strain. However, after missing the remainder of the team's weekend series, it doesn't appear as though we'll be seeing the 22-year-old back on the field for quite some time.
