Grandal has been sent for additional tests on his forearm, Andy McCullough of the Los Angeles Times reports.
While Grandal said that he will play Thursday, the team has not yet confirmed a return date. Manager Dave Roberts said the lingering discomfort in Grandal's forearm is "disconcerting," and it seems the club wants to get a better idea of what the problem is exactly. Grandal recently suggested the soreness was the result overworking in the batting cages.
