"There's a good chance of that, but he can show up tomorrow and be ready to go," Bochy said before Saturday's game. "It's up to how much progress he makes in this next day."
Cabrera injured his right hamstring Thursday while stealing second base in the seventh inning of an 8-3 win against the Padres.
"We'll keep checking on him and he'll get treatment, and that'll continue through today's game and through tomorrow," Bochy said.
Bochy said Cabrera could be available to pinch-hit in emergency situations, but he is wary of rushing the National League's current batting average leader back.
"As much as you'd like to have him out there, you don't want to have any setbacks and lose him for any extended periods," Bochy said.
