Locke is dealing with biceps tendinitis and won't throw for the next three days, Clark Spencer of the Miami Herald reports.

EDGE Analysis

Locke's injury isn't considered a long-term issue, so the Marlins will take a conservative approach with his usage in the early days of spring training. Assuming Locke is able to resume throwing next week, he shouldn't find himself too far behind the rest of the Marlins' other starting pitching options as he looks to claim a rotation spot to open the season.
