Giants first baseman Brandon Belt is reportedly undergoing concussion tests on Saturday night following his early exit from San Francisco's 5-3 win in Miami against the Marlins, Henry Schulman of The San Francisco Chronicle tweeted. 

The 26-year-old left the game in the third inning due to dizziness after belting an RBI double and scoring a run. Initially, media reports had said he left the game due to back stiffness; he was scratched earlier in the week with a stiff back

The Giants are first in the NL West heading into their series finale in Miami on Sunday. It's not immediately known when Belt will be available.
