Hull Live can reveal it’s not the first time the RFL have granted such a request. Clubs have been able to seek dispensation for full season injuries occurred in pre-season since the beginning of the 2016 campaign.
It’s understood clubs have to submit medical evidence regarding the injuries and if successful, said player’s salary is taken off the cap. It’s a ploy that has been utilised on several occasions by clubs over the last three years.
Yet they don’t name a single player. So they can reveal it happened, they just can’t reveal any actual examples. So reality is they don’t know for sure it’s happened.
