Posey will not start Saturday's game against the Astros, Alex Pavlovic of NBC Sports Bay Area reports.

EDGE Analysis

Posey missed Thursday's game against the Dodgers after taking a foul tip off his mask the day prior, but he returned to the lineup Friday to go 2-for-4 with a walk, two runs scored and an RBI. He certainly looked healthy, and the Giants haven't indicated that Saturday's absence is anything other than a routine one for the veteran backstop. Curt Casali will catch Alex Wood in his absence.
