Cubs starter Yu Darvish felt fine the day after his simulated game, but the Cubs haven't announced his next move.
"He's feeling good today, so it's all optimistic now," manager Joe Maddon said.
General manager Jed Hoyer said Wednesday that Darvish could go on a rehab assignment as early as Monday, but nothing is set in stone.
Darvish said he needs only one rehab start, but Maddon said that will be determined by how he throws.
"You could say that's a possibility, and if a guy goes out and nails it down and throws a requisite number of pitches, then you might be able to do it. But I still think it should be a one-moment-at-a-time thing."
Triple-A Iowa and Double-A Tennessee are on the road next week, so Darvish could be sent to Class A South Bend, depending on the weather.
Maddon still doesn't have a starter for Saturday or Sunday in Cincinnati. Tyler Chatwood's wife is expected to give birth any day, so he's not a certainty to start Sunday.
"There's nothing we can do about it," Maddon said. "We want to make sure everything works out well for the Chatwoods, and then we'll make our decisions."
Luke Farrell could start Saturday, but he could be used in relief in the next two days. The weather also may be a factor, with rain expected all weekend.
