Very much doubt there isn't one. Very much doubt we'll be planning on using it, but the idea we wouldn't have put one in just in case (just in case he wasn't getting any game time, or just in case we had a massive injury crisis, for example) seems unbelievable.Very much doubt there is any recall clause. Not happening
Edit: Sorry - I now see I'm just echoing what's been said (quite rightly) already.
