Montas (ribs) is expected to return in September, J.P. Hoornstra of the Southern California News Group reports.
The Dodgers plan to use Montas from the bullpen when he returns from his injury. He's had mixed results as a starter this season, allowing six runs in his first outing, then just one in his second. However, he's been a reliable option from the bullpen, where he owns a 1.13 ERA.
