It has been revealed that Jack Stevens, son of 1980s Everton legend Gary, has suffered a relapse in his fight against leukaemia.

Jack was diagnosed with the blood cancer last year and a GoFund me effort raised AUD$64,000 to help pay for potentially life-saving treatment.

While the early signs were promising, it is now the case that Jack desperately needs to find a stem cell donor.

Gary and his family have requested that all Evertonians register as a donor in the hope that a match can be found so if you are under 45 in particular (research suggests that younger stem cell donors offer a much better chance of long-term survival but some of the organisations will accept over-45s as donors), you can sign up at wmda.info, DKMS or at anthonynolan.org.

There is also a new GoFundMe page if you would like to donate to Jack's cause.
