UPDATE: The Diamondbacks reported Robbie Ray's CT scan was normal. He received a few stitches and returned to the team's hotel to rest. He will be placed in concussion protocol.

--------------------------------------

Arizona Diamondbacks All-Star pitcher Robbie Ray left Friday night's game at the St. Louis Cardinals after getting hit in the head by a line drive.

Ray immediately went to the ground holding his head following the hit 108 mph by Cardinals first baseman Luke Voit in the bottom of the second inning. He eventually sat up but remained on the ground for several minutes before being carted off the field.

Ray waved to the St. Louis fans, who gave him a standing ovation, as he exited the field. The D-backs reported was taken to a nearby hospital for further testing.
