Eveland was informed of the decision early Wednesday and will make his first start of the season for the Dodgers against Pittsburgh, after a solid season with Triple-A Albuquerque.
Though he scuffled a bit in August, Eveland was the Isotopes' most reliable pitcher, going 12-8 with a 4.38 ERA and two complete games.
The 27-year-old last made an appearance at the big league level as a reliever for the Pirates last June. His last start came at PNC Park on June 7, 2010. Eveland has pitched for six teams before in his six seasons in the Major Leagues.
The Dodgers had made the decision a few days ago, but waited until Wednesday to let Eveland know. On Wednesday afternoon Eveland flew to Pittsburgh, where he will meet up with the team.
With rosters expanding Thursday, Mattingly acknowledged there will likely be a couple other roster moves. Shorstop Dee Gordon, out since Aug. 9 with a bruised shoulder, will be activated from the disabled list, and Mattingly said the team could also add another infielder.
That would likely be utility man Russ Mitchell, who had three hits, including a homer, in 26 at-bats with the team in May.
