Dak not riding next year too look after his Father.
Off the rest Magnus Karrlsson & PK ride Swedish League on Thursday's well they did last year so no reason to presume they won't this as they rode in both division's , Gomolski has a Polish Licence so wouldn't be allowed to ride PL without consent which is unlikely.
So from that list Fisher would be the only realistic signing as Bjerre senior will not be riding PL and if he does it will be with Peterborough.
