Mike Riley has talked in the press of 'more promotions to SG1' to take account of the need next season for additional cover for VAR duties. So it seems the powers-that-be are going to be using SG1 refs for VAR work in the PL rather than SG2s / FLs or former refs. Looks promising imo for the likes of R Jones, A Madley and perhaps Messrs Bond, England and Robinson.
