NEW YORK (AP) — Yahoo's new chief executive, Carol Bartz, may announce a management restructuring as early as Wednesday, according to The Wall Street Journal.

The Journal, citing unidentified people, said in a report published on its Web site Saturday that a memo from Bartz suggested there would be a reorganization and that many top executives knew few details about it.

Bartz is likely to undo or scale back prior reorganizations by former CEO Jerry Yang, the paper said, citing the expectations of many.

The paper said, citing several sources, that former President Sue Decker's chief of staff, Jeff McCombs, has already left Yahoo.
