Giants' Posey in lineup Thursday vs. Marlins after passing concussion test

Buster Posey will not miss any time after an injury scare Wednesday.

The San Francisco Giants catcher is in manager Bruce Bochy's lineup Thursday versus the Miami Marlins, one night after taking a foul tip off his mask that forced him out of action.

Posey passed a concussion test after Wednesday's game, and will receive a break from behind the plate Thursday, manning first base for the Giants.

Posey is hitting .304 with 12 home runs and 54 RBIs in 76 games.
