Buster Posey placed on seven-day concussion disabled list (Yahoo Sports)

Catcher Buster Posey was placed on the seven-day disabled list with concussion symptoms Tuesday, a day after he was struck in the helmet by a 94 mph fastball from Arizona's Taijuan Walker. While manager Bruce Bochy said following Monday's 4-1 victory that Posey was doing fine, the Giants planned to check in with him overnight and re-evaluate him Tuesday. Athletic trainer Dave Groeschner sprinted toward the plate and manager Bruce Bochy was right behind.
