The team activated catcher Brian McCann from the disabled list. McCann, returning from a strained left oblique, is starting in Sunday's game against the Chicago Cubs.
Hanson allowed seven runs in 3 1/3 innings in an 11-7 loss at the New York Mets on Aug. 6. An MRI on his shoulder showed no structural damage.
Jair Jurrjens (right knee strain) is eligible to come off the disabled list Tuesday, when the Braves will need a starter to replace Hanson.
