Kuo threw another bullpen session on Wednesday, and the reports again were positive.
"He felt good," said Dodgers manager Joe Torre. "Here in the next couple of days we'll probably activate him. We just want to be sure."
Kuo's return will necessitate an additional roster move. Torre didn't bite when asked who might be moved.
"We have a couple of options," he said. "I don't know for sure. It's not that I don't want to tell you. I simply don't know yet."
