"If I feel fine, I'll continue to swing the bat, and hopefully I'll be ready soon," Franco said.
"Once he does that -- getting a few at-bats and taking some batting practice -- I might run him right in there if he's 100 percent," interim manager Pete Mackanin said.
Some other injury updates:
• The season is officially over for right-hander Chad Billingsley, who has been on the disabled list with a strained flexor in his right elbow.
"It's unfortunate," assistant general manager Scott Proefrock said. "We had high hopes for him coming back. He had made a lot of progress. It just didn't work out for us."
Doctors said that Billingsley, who tried to come back following a pair of operations on his right elbow, does not need surgery.
• Lefty Elvis Araujo is on the DL with a strained left groin, and it is unlikely that he will pitch again this season.
"I think [we're exercising] an overabundance of caution," Proefrock said. "He's done very well, and he's got a chance to be a piece for us going forward. There's no reason to take any unneeded chances with him."
