ATLANTA -- The ominous-looking injury Giants third baseman Pablo Sandoval suffered Monday night when he fouled a ball off his right foot should have no lingering consequences, since X-rays taken of the afflicted area revealed no structural damage.

Nevertheless, Giants manager Bruce Bochy expected Sandoval to be sidelined for one or two days.

"The good news is the X-rays were negative. But he's going to be hurting for a while," Bochy said.

Said Sandoval, "We'll see what happens day by day."

The Giants can ill afford to lose Sandoval for any period of time. He leads the National League's lowest-scoring club with a .309 batting average and a .515 slugging percentage.

Sandoval fell to the dirt in extreme pain after hammering a 1-0 pitch from Atlanta right-hander Tim Hudson almost straight downward and off the side of his foot during the first inning of San Francisco's 5-4 loss. Bochy and head athletic trainer Dave Groeschner ran out to check on Sandoval, who remained in the game and reached first base on a fielder's-choice grounder. But utility infielder Mike Fontenot replaced Sandoval at third base in the bottom of the inning.

Sandoval missed 40 games earlier this season after fracturing his right hamate bone and undergoing subsequent surgery, but still made the NL All-Star team.
