Oakland Athletics righthander Brandon McCarthy was hit in the head with a line drive off the bat of the Angels’ Alberto Callaspo during Wednesday’s game. According to Joe Stiglich of the Oakland Tribune, that wasn’t the only hit he took:

McCarthy banged the back of his head on the ground when he landed, and though he sat up quickly, he appeared dazed as A’s head trainer Nick Paparesta rushed to check on him.

Though McCarthy eventually walked off the field under his own power, he appears likely to miss at least one start. He’ll be examined further:

McCarthy was scheduled for a CT scan at nearby Summit Medical Center, and the A’s issued a statement Wednesday night saying McCarthy was conscious and doing well but would stay overnight for observation. He will not fly on the team charter Thursday to Seattle.

McCarthy’s next start is scheduled for Tuesday in Anaheim. A’s manager Bob Melvin didn’t want to speculate on whether McCarthy would miss time, but given the delicate nature of any head injury, it would appear the pitcher could be sidelined for Tuesday’s outing and perhaps longer.

The A’s are already down one starting pitcher due to the PED-related suspension of Bartolo Colon. They’re in a tight race for an AL wild-card spot and can ill afford to lose McCarthy for too long.
