Hargreaves was due to play in a reserve team encounter with Manchester City last night and end a near-18 month absence following a double knee operation.
But United officials confirmed on Wednesday night that the England international would not be involved, as it interfered with his training regime.
It seemed a strange explanation. And Ferguson has clarified the situation, pointing out that Hargreaves in fact went to see a specialist for the latest update.
However, as the verdict was positive, Ferguson believes an end to Hargreaves' lengthy spell on the sidelines is in sight.
"Owen went to see a specialist yesterday," said the United boss.
"There is nothing wrong and the idea is for him to play in the next game.
"He has to play in the next game because he is ready to play."
United's reserve side is next due in action on Thursday, when they entertain Burnley at Altrincham's Moss Lane ground.
However, given this week's events, nothing should be taken for granted until the 29-year-old actually makes an appearance.
