As of now, Belt's estimated absence remains six weeks. Bochy said that the pins likely will be removed after four weeks, and at that time the Giants should know more clearly how long Belt will be sidelined.
"You'll have a better idea of how much he can do," Bochy said. "That tells us how much he can ramp up his rehab."
Belt was injured in Friday night's series opener against Los Angeles when Dodgers starter Paul Maholm struck him with an 87-mph fastball.
