"He's never had a headache. He's never had dizziness. Nothing," Rand said. "He's had no symptoms at any time."
Fister was struck in the head during Thursday’s Game 2 by a line drive off the bat of San Francisco Giants outfielder Gregor Blanco. While the Tigers were concerned over the delayed onset of a concussion, Fister didn’t show signs Thursday or over the past two days of tests.
Fister didn’t undergo a CT scan or MRI because of the lack of symptoms, and because he’s passed the tests by the doctors and trainers he’s been cleared to work out and pitch.
