Concussion forces Giants first baseman Brandon Belt to DL

San Francisco Giants first baseman Brandon Belt will go on either the seven-day or 15-day disabled list because of a concussion.

Belt was struck by a ball in the face while fielding during batting practice Saturday. Tests Sunday confirmed the concussion, manager Bruce Bochy said.

Infielder Adam Duvall will likely be recalled from Triple-A Fresno, Bochy said.

Belt was to fly with the Giants to Philadelphia, where they begin a four-game series Monday. He missed 50 games because of a broken left thumb before returning July 5.
