Houser was removed from Tuesday's game against the Red with an apparent arm injury, Alex Pavlovic of NBC Sports Bay Area reports.
Analysis:Houser's arm began giving him trouble after he made a pitch during the second inning, and manager Tony Vitello made the call to take him out of the game immediately afterward. It's unclear what exactly the right-hander is dealing with, but the Giants should provide an update on his status after they get a closer look at him.
