National sweetheart Lowery sadly “died in his mummy and daddy’s arms” aged six on Friday following his brave fight with a rare form of cancer.
Lowery led out the Black Cats as a mascot with Jermain Defoe, who became his “best friend” last season, before also walking out with his hero for England’s victory over Lithuania in March.
The Championship club faced the Shakers in a pre-season friendly on Friday and both sides agreed to pay tribute to Bradley.
All gate receipts from the friendly – which Sunderland won 3-2 – will go to Bradley’s charity.
Bury tweeted: “Everyone at Gigg Lane is deeply saddened to hear the news regarding Bradley Lowery this afternoon after such a brave fight….
“We will be holding a minutes applause for Bradley ahead of this evenings game with @SunderlandAFC to pay our respects to him and family.”
Earlier, the Black Cats had posted a tribute to Bradley on their website.
It read: “Our thoughts and prayers are with Bradley’s parents, Gemma and Carl, his brother Kieran and their family and friends. We extend our love and support to them, now and always.
“Bradley captured the hearts and minds of everyone at our club with his indomitable spirit, tremendous courage and beautiful smile, which could light up even the darkest of rooms. Despite battling neuroblastoma for much of his all too short life, he demonstrated a bravery and fortitude beyond his years that humbled us all. He was truly an inspiration.
“His heart-warming friendship with players and staff alike epitomised the impact this wonderful little boy had on everyone he met. He had a special relationship with Jermain Defoe and their feelings for each other were evident for all to see. Jermain, naturally, is heartbroken.
“Bradley’s story not only touched our club and our fans, but also the wider football community. Football can be a powerful force for good and our sport came together to embrace Bradley’s fight in a unique way.
“We would like to extend our sincere thanks to every club and fan who supported Bradley in recent months and showed such warmth and kindness to the Lowery’s – we are truly grateful.
“Throughout his illness, Bradley’s family and friends have worked tirelessly to increase awareness of this brutal disease. Their fundraising campaign, initially for Bradley’s treatment and subsequently to raise money for the foundation that will bear his name, will ensure that other youngsters and parents facing the devastation of life-threatening illnesses will have the help and support they so desperately need.
“Bradley’s passing will have a profound effect on everyone and we understand that people will want to reach out to support the Lowery’s.
“We would kindly ask on their behalf however, that that they are given the privacy they need as a family at this most unimaginably difficult time. We will continue to support them in whatever way we can.”
