SAN FRANCISCO -- The San Francisco Giants placed left fielder Nori Aoki on the seven-day concussion disabled list and recalled outfielder Ryan Lollis from Triple-A Sacramento in a corresponding move.
Aoki, who was hit in the helmet with a Jake Arrieta fastball on Sunday, missed Tuesday's game against the Astros and returned to the lineup Wednesday afternoon. However, Aoki felt lightheaded throughout the first few innings and exited the game after the fourth.
Aoki was not officially diagnosed with a concussion, but because he experienced symptoms of one, the team did not want to take any chances.
