The move Wednesday leaves the Stars with two goalies: Turco, in the last season of his contract, and Kari Lehtonen.
The acquisition of Lehtonen from Atlanta earlier this month had created speculation that Turco might be traded, but Turco was 4-1-1 with a 1.15 goals-against average and a .967 save percentage in his last six games before the Olympic break. In 43 games overall, he has a 2.63 GGA and a .915 save percentage.
Auld had a 3.00 GAA and .894 save percentage in 21 games.
The Stars resume play Tuesday just one point out of a playoff spot.
