It sounds stupid doesn't it. The only thing I can think of is that he's on the EFL squad list as a Sheff Wed registered player rather than registered to us, so bringing him back would mean re-registering him to us with the EFL?

It looks like that would be allowed under the EFL embargo rules but not FIFA's.
What happens if he stays with them until the summer and the embargo is still in place though? His loan deal will have expired so he can't play for them, but we can't re-register him so he can't play for us either?
