Huff has been sidelined since Matt Cain's June 13 perfect game, when Huff sprained his right knee when he fell during postgame celebrations.
"I talked to him a little bit today, and he's doing a lot better," Bochy said. "He's getting close, and he's able to do some stuff now. He's making a lot of improvement."
Counting Monday's game, Huff has missed 11 games since being placed on the disabled list with the knee injury, and Bochy said a Minor League rehab assignment will be likely.
"We really haven't talked about it, but I do think it'll be a good idea for him because he's missed so much time," Bochy said. "That's something Aubrey and I need to talk about."
Huff, who was also on the DL earlier this season with anxiety disorder, is batting .155 this season in 58 at-bats with only four extra-base hits and five RBIs, but Bochy said Huff will continue to have a role as a left-handed bat off the bench.
"That's the plan right now -- have him available for the occasional start, have him come off the bench and bring experience," Bochy said. "Being a [former] DH gives him experience coming off the bench and being a pinch-hitter. It also gives us depth, and if something happens where he's swinging well, we'll have another proven bat to put in the lineup."
