"[Corporan] was feeling nauseated and feeling a little dizzy," Astros manager Bo Porter said. "When they started talking to him in the dugout, he was slow to respond."
Corporan said after the game the club will test him for a concussion on Tuesday. The Astros lost their designated hitter in the eighth when Elmore made his first Major League appearance as a pitcher and DH Jason Castro moved behind the plate.
It was Corporan's 39th start as a catcher this season, and he went 0-for-1 at the plate.
