An announcement which may lead to 1,000 job losses and the night-time closures of two hospital casualty departments has been delayed for a fortnight.
Lincolnshire health managers have been trying to address an overspend of more than £17m.
Union leaders fear up to 1,000 jobs will go. Accident and emergency departments at Boston and Grantham hospitals may be closed at night.
But the Department of Health has asked for further details of the proposals.
An announcement is now expected in the middle of June.
A meeting of the trust board which runs the county's hospitals also heard that changes already put in place had reduced the monthly overspend from £2.5m to £1.3m.
