Anyone know what the rules are on this ?

As I understand it( and I'm no expert) , we can sign a free agent at any time. It seems with the injury list right now that this might be a good idea.

Now, here's the question. If a co operative club were to terminate a players contract with immediate effect, much as we did with NML, would that mean that he'd become a free agent and that, urgo, we could sign him ?

There must be many players in the required positions who aren't getting into the team and who aren't going to get a new contract.
That'd solve a problem - is there any rule to prevent it ?
