Doubront has been dealing with some arm fatigue and a right knee contusion, and the move was made retroactive to Aug. 10.
That would set Doubront up for a return to the rotation in one week -- Aug. 25 at Fenway Park against the Royals.
By placing Doubront on the DL, the Red Sox were able to add another bat to the mix, bringing back Mauro Gomez from Triple-A Pawtucket.
At a time when David Ortiz is still on the DL with a strained right Achilles tendon, Gomez could offer the Red Sox some production.
Gomez, 27, hit .300 (9-for-30) for the Red Sox over nine games in his earlier stint this season. The International League All-Star is leading that league with 59 extra-base hits, a .589 slugging percentage and an average of 16.13 at-bats per home run.
Though third base -- and defense in general -- is hardly Gomez's strength, he did play a couple of games there earlier this season for Boston manager Bobby Valentine. That could come in handy now with Will Middlebrooks out for the rest of the season with a broken right wrist.
