Blackmon, who left Thursday's game against the Pirates in the fourth inning, is dealing with a right calf issue, Patrick Saunders of The Denver Post reports.

EDGE Analysis

Manager Bud Black said it is something the team is "monitoring", so the severity is unclear. For now, he should be considered day-to-day. Ian Desmond, who replaced Blackmon in center field, would likely get starts in the short term, but if the issue requires a stint on the injured list, Yonathan Daza could be an option to join the team from Triple-A Albuquerque.
