The left-hander was diagnosed with tendinitis in his posterior shoulder last week and was removed from his outing Wednesday against the Boston Red Sox.
After a game of light catch in the outfield Saturday and a regular bullpen session Sunday, Sale said he has zero issues heading into his next outing.
"Not only was it good for my shoulder, but my elbow feels great too not throwing for a few days," Sale said. "My body feels better, so hopefully this will last for the rest of the season."
There will be no restrictions on this season's Opening Day starter, who hasn't taken the mound since May 17 when he went 7 2/3 innings in a road victory against the Los Angeles Angels.
"He said he's ready to go; he says he feels good," manager Robin Ventura said. "I think it was one of those things where it's nice to get him that break of an extra few days. And he feels stronger, which is good news."
The only game the White Sox lost of the six on the current homestand was the one Sale missed, but the team isn't going to complain about the extra rest for its staff ace. Sale is still on pace to pitch more than 230 innings.
As for any rust Sale might have by going 11 days between starts, he isn't going to worry about it at this point.
"It's something that's definitely not a focus point right now," he said. "I'm worried about going out there and winning a ballgame and not how bad I might be. I just knocked the rust off the last couple of days and hopefully it was enough."
