Staff at United have pulled together to raise funds for the family of club mascot Captain Blade after his granddaughter travelled to Oklahoma for potentially life-saving cancer treatment.
Two-year-old Chloe Squires, of North Anston, was diagnosed with Rhabdomyosarcoma, a rare type of cancer, in November.
She has since undergone numerous rounds of chemotherapy before she flew out to Oklahoma with her mother Natalie to undergo proton beam therapy treatment. It is estimated that they will remain in America for up to nine weeks.
The treatment works by directing radiation treatment to precisely where it is needed in the body and causes minimal damage to surrounding tissue.
Although the treatment is not currently available in the UK, the NHS are funding the cost of Chloe's treatment, travel and accommodation but the day to day expenses and rehabilitation costs must be met by the family.
The family set up a JustGiving Yimby page, which gives a 30-day deadline to raise any funds required, in an attempt to raise £1,000 to help cover these costs.
Upon hearing about the fundraising efforts of Captain Blades' family, Sheffield United staff -including first team players, coaches and vice-presidents - donated what was required to reach the £1,000 target just hours before the website's deadline.
Captain Blade said: "Everyone in my family is overwhelmed and deeply moved by the generosity of the Club.
"All Club staff have got behind our fundraising, donating items for auction and making personal donations through our online page. We can't thank them enough.
"Any additional money raised and not used will be donated on to other children suffering with cancer and to Sheffield cancer wards treating children."
Dave McCarthy, operations director at Sheffield United, said: "We wish the family of Captain Blade all the very best as his granddaughter Chloe undergoes cancer treatment in America.
"Sheffield United will always pride itself on being a family club and we're delighted to help one of our own."
Chloe's treatment will be performed by Dr Andrew L. Chang, a leading oncologist and global specialist in cancer treatment who is based at the ProCure Proton Therapy Centre in Oklahoma and provides proton treatment to about 50 UK patients each year.
