Chicago Cubs All-Star Kyle Tucker left Tuesday's game against the Atlanta Braves in the seventh inning with calf tightness.
It's not clear when or how Tucker sustained the injury. He met with a trainer in the Cubs dugout after hitting a single in the bottom of the fifth inning. He returned to his spot in right field for the top of the sixth, but was replaced in the field by Willi Castro in the seventh.
The Cubs later announced that Tucker was dealing with left calf tightness.
The severity of Tucker's injury wasn't immediately clear.
