Newcastle will be able to sign players on loan from sides also controlled by their Saudi owners in January, after a vote by Premier League clubs on a temporary ban on related-party loans did not receive the required support.
Thirteen clubs voted in favour of a block on loan moves between teams under the same ownership.
That was one short of the two-thirds majority needed for it to be passed.
The Premier League was understood to be in favour of introducing the ban.
It means Newcastle United, for instance, could sign players from clubs also owned by Saudi Arabia's Public Investment Fund (PIF).
