Definitely true of the Prem league.
EFL -You used to be able to on the short term loan basis if the other club agreed:
52.7 During the period of any Temporary Loan Transfer, a Player shall not play against his Transferor Club without the prior written permission of the Transferor Club (which, if given, must be indicated on the appropriate Temporary Loan Transfer form).
I thought short term loans referred to the 30-90 day types that were outlawed this year. In which case I can't find the right rules!! I can't find restrictions under a standard loan in the rules I can find.
That's a long way of saying who the fuck knows.
