Peavy threw an easy 34-pitch bullpen session at U.S. Cellular Field on Saturday and will now head out for a minor league rehab start at Double-A Birmingham.
One last minor league start is set for next Saturday, April 23, and is scheduled for Triple-A Charlotte.
Peavy would then be in line to start for the White Sox on April 28 at Yankee Stadium in the finale of a three-city, 11-game road trip, but he doesn't sound interested in coming back on that day.
"That's Johnny Danks' day," Peavy said.
Barring any rainouts or rotation changes, Philip Humber would be in line to open the next homestand on April 29. Peavy coud replace Humber in the rotation that day, or Humber could pitch, leaving Peavy to return the following day on a full week of rest.
By giving Humber one last start, it would give the other members of the rotation an extra day of rest during a stretch when the White Sox are scheduled to play 20 games in 20 days.
"I'm excited to [return to the major league rotation] but I guess I'm at ease with the plan," Peavy said. "I'm doing what I'm asked to do and told to do and I'm at peace with pitching Monday and Saturday and if they think I'm ready after those two -- and I certainly think I will be -- I can't see me not starting."
