Around 59 million euro has been allocated from the British government to the redevelopment of Casement Park.
It means there's still around 100 million euro of a shortfall for the long-awaited project - following commitments from Stormont, the GAA and the Irish government.
Last year, the British government pulled out of funding the project in time for Euro 2028.
The GAA says there is more work to do to get the stadium completed and will work on delivering a full funding package.
First Minister Michelle O'Neill says today's announcement is a significant step.
