Elbert has been out since July 26 with left elbow inflammation that he believes might require a minor arthroscopic cleanup procedure in the offseason.
He struck out one in a perfect ninth inning to close the Dodgers' 5-0 win over the Braves on Sunday.
The move leaves the Dodgers with eight relievers and only four bench players. But with relievers Brandon League and Javy Guerra struggling, management apparently felt it needed an extra piece in the bullpen more than an extra fielder, especially with Luis Cruz essentially taking over the third-base job.
That leaves first base as the only real platoon spot between James Loney and Juan Rivera. Adam Kennedy and Juan Uribe are the utility infielders, Rivera the fourth outfielder and Matt Treanor the backup catcher.
Herrera was called up Aug. 13 when Jerry Hairston was sent to the DL.
