Rather than starting Danks on Monday against the Cubs, the White Sox have listed Jake Peavy as the scheduled starter.
Danks said he spoke to team doctor Gregory Nicholson, whom he'll see Monday in Chicago. Danks said he is unsure when he'll next throw a side session. He last pitched on Tuesday in a rehab outing with Triple-A Charlotte. He allowed three runs (one earned) and threw 61 pitches in four innings.
"We're doing everything we know to do to make me feel better," Danks said. "I haven't quite gotten over the hump yet. Keep doing what we're doing and play it by ear."
Danks said he didn't throw for very long on Friday because he was so sore Thursday. He has been on the disabled list since May 25, retroactive to May 20, for a left shoulder strain.
"My strength is there," Danks said. "I just got to get to that point where it doesn't hurt or bother me to throw. We haven't quite got all the way there yet. There's some real good days, and there are days like [Thursday]. I'm just kind of at the mercy of what my shoulder tells me."
The White Sox are being cautious with their Opening Day starter, who is 3-4 with a 5.70 ERA.
"It's one of those things you extend it and make sure he's healthy first," manager Robin Ventura said. "We just don't want to rush it. We're going to continue to be patient and make sure he's healthy."
