Aoki is expected to be out "a while" due to post-concussion syndrome, according to John Shea of the San Francisco Chronicle.

EDGE Analysis

The 33-year-old spent a week on the concussion DL in mid-August, but returned to start each of the team's final 11 games of the month. His symptoms have reportedly resurfaced, however, and Aoki has been forced out of action yet again. It's uncertain if he'll make it back before the end of the season.

Aoki is not in the lineup for Saturday's game against the Rockies.

EDGE Analysis

Saturday's absence from the lineup marks Aoki's fourth straight. He sat the last three games with the Giants facing three consecutive left-handers, but he'll remain on the bench against right-hander Chad Bettis. Alejandro De Aza gets the start in left.

EDGE Analysis

Aoki will receive an off day with the left-handed Chris Rusin toeing the rubber for the Rockies. As a result, the Giants will give Juan C. Perez the start in left field in his place, batting seventh for the Giants.

Aoki is not in the lineup for Tuesday's game against the Dodgers.

EDGE Analysis

On the heels of a .208/.282/.390 month of August, Aoki will take a seat for the first game of September as trade acquisition Alejandro De Aza takes over in left field against right-hander Zack Greinke. Given Aoki's second-half struggles, it seems likely he will be limited to some sort of timeshare moving forward, and his opportunities to lead off will take a hit with Angel Pagan back on the roster.

San Francisco Giants outfielder Norichika Aoki left Wednesday's game against the Houston Astros after feeling lightheaded, according to the San Jose Mercury News. Aoki played Wednesday for the first time since being hit by a pitch on the helmet over the weekend, but he could be placed on the 7-day concussion disabled list after the latest bout of concussion-like symptoms. Giants manager Brucy Bochy said after the game, "We're treating him at this time for a concussion. He showed symptoms. He'll get re-evaluated and we'll decided what we're going to do." It sounds as though the Giants will not make a decision on whether or not to place Aoki on the disabled list until Thursday, though Ryan Lollis and Jarrett Parker are reportedly options to replace him should he be sidelined. Aoki is batting .304 with four home runs, 24 RBI and 12 stolen bases this season.
