Peavy will start for the first time since June 4 on Saturday when the White Sox host the Braves, who could have Heyward back in the lineup.
Chicago (37-56) activated Peavy (6-4, 4.30 ERA) from the disabled list Friday. He was out with a fracture of the left fourth anterior rib, but there won't be many restrictions on him after a stint in the minors.
"As long as his rib is doing fine, he can stay in there,'' manager Robin Ventura said. "If it was something with an elbow or shoulder or something like that, you'd be a little more sensitive to him being out here in this heat and doing things. For Peav, you just let him go.''
Peavy expects to be limited to around 100 pitches Saturday. He allowed one run in five innings of a start for Double-A Birmingham on Sunday.
"I threw about 85 (pitches) in the rehab start in Alabama," he said. "I did get a little tired in that start, but it's something I've addressed with the skipper and we'll monitor closely."
Peavy, 3-0 with a 1.88 ERA in four home starts, went 2-4 with a 3.97 ERA in seven outings versus Atlanta (55-41) between 2003-08 for San Diego.
The right-hander has never faced Heyward, who began his career in 2010 and has missed four straight games with a strained right hamstring. Heyward says he is close to returning.
"Every day it feels better once I get to the field and get loose," he told the Braves' official website. "It feels that much better, so soon … real soon."
Justin Upton is 4 for 6 with a homer and a triple against Peavy. The outfielder went 2 for 4 with two runs in a 6-4 victory Friday that opened this three-game set, returning after missing two games with a sprained left calf.
The Braves ended a five-game slide to the White Sox - all on the road. Brian McCann had the big blow as he homered for the third straight game, hitting a three-run shot in the sixth inning.
The White Sox are an AL-worst 7-16 against left-handed starters as they get set to face Paul Maholm (9-8, 3.98). He's 1-2 with a 4.66 ERA in three outings against them and has never pitched at U.S. Cellular Field.
Maholm owns a 5.37 ERA on the road compared to 1.93 at home. The Braves have dropped five of his last seven outings.
He has plenty of experience facing Adam Dunn, who is 4 for 31 with one homer and 13 strikeouts against him.
Ventura pulled Alex Rios in the seventh inning Friday after the outfielder didn't hustle on a double-play ball. Rios is 2 for 20 since his career-high, six-hit effort July 9 against Detroit.
"There is just expectations and we are not starting the second half off that way," Ventura said. "It was simple, he will be back in (Saturday). Tonight, that's what happens when you don't run.''
The White Sox, losers of 14 of 19, are an AL-worst 6-12 in interleague play.
