Seconded. Good player who had some bad luck with injury.
As to the quota I think it was already factored in. It’s not really an overseas quota now anyway. It’s a limit on how many non-federation trained players a club can have which stops clubs doing as they used to and having a full quota and then a string of Kolpak players who didn’t count on the quota. I think Bradford took that to extreme at one point.
I am pretty sure we have a full non-fed trained quota so Cust’s fate was sealed weeks ago. I presume it’s only been announced officially now he has secured a club which is good from Wigan not announcing he’s just been let go. That would be a poor thing to do so a bit of class from Wigan there.
Anyway back to Cust. As Fozzie said, that is the way to leave a club. Contrast it with the dummy spits of other fairly recent departures such as Hardaker and even Bateman who messed the club about.
