Newcastle could block the transfer of David de Gea from the Premier League.
The Magpies want to sign the former Manchester United goalkeeper after their No.1 Nick Pope picked up a shoulder injury in the 1-0 win over the Red Devils.
It was a recurrence of an earlier shoulder problem for Pope, who will undergo surgery and is expected to be out for four months.
Pope’s injury is a huge blow for Newcastle, given the way he has performed since joining from Burnley.
De Gea, who is still a free agent after leaving United after his contract expired in the summer, was considered a possible option.
The Spaniard is said to be open to a return to the Premier League, although his wife Edurne Garcia wants to stay in Spain.
Newcastle still have three goalkeepers on their books in Martin Dubravka, Loris Karius and Mark Gillespie.
And according to Chronicle Live, the Magpies will have to get special dispensation from the Premier League.
Typically this will be given in an emergency scenario where there is only one known gatekeeper.
And the rules state that changes to squad lists cannot be made outside the transfer window without the approval of the Premier League.
