Loan players

Is there a procedure for calling back loan players if they are no longer needed by the club they have gone to. I was thinking of if we fail to go up automatically it would be more than useful to have a fit Tomlin back for the play offs. Forest wont need him.

I assume he would be back as Forest's season would be over

but if he signed on loan until end of season -which may includes date after the play offs- we may not be allowed to play him even if forest are happy to send him back.
