Manager Skip Schumaker said Curvelo exited Saturday's game against the Guardians with a left thigh injury, Matt Postins of SI.com reports.
Curvelo was struck on the inner thigh above the knee by a comebacker off the bat of Patrick Bailey in the top of the eighth inning and was immediately removed from the game after he fell to the ground following a bad throw to first base on the play. "He wasn't feeling really good," Schumaker said. It's unclear if Curvelo will need a stint on the injured list.
