"He's available to pitch today, but ideally we'd like to get him off today, and tomorrow's a day off," Bochy said. "We think he'll be ready on Friday."
Romo injured his patella while stretching prior to Monday's game, and an MRI confirmed the partial dislocation.
"He's walking around and he's in the dugout," Bochy said. "We just don't want to put him on the mound."
Bochy said everyone else was available to pitch out of the bullpen, even closer Santiago Casilla, who had saved each of the Giants' last three games.
"I'll tell you I'd like to stay away from Casilla, but he's going to tell me he's fine," Bochy said. "It'd be nice to give him a couple days [off]; he's gone three in a row."
