This is certainly good news for the Braves, who have seen Jonny Venters and Eric O'Flaherty undergo season-ending Tommy John elbow reconstruction surgery over the past week. Venters, O'Flaherty and Walden entered the season projected to serve as closer Craig Kimbrel's top setup men.
Braves manager Fredi Gonzalez said Walden will complete a bullpen session later this week and then make at least one Minor League rehab appearance before being activated.
Walden was placed on the disabled list on Friday (retroactive to Sunday) with right shoulder inflammation. After producing a pair of impressive scoreless outings against the Nationals on April 29 and May 2, the 28-year-old reliever allowed at least one run in each of his next three appearances.
"I tried to pitch through it," Walden said. "But it gets to a point where you are just hurting the team and hurting your arm."
When Walden returns, he could team with left-hander Luis Avilan and right-handed sidearm reliever Cory Gearrin to serve as Kimbrel's top setup men.
