Lowery was just two when he was first diagnosed with the life-threatening illness. His parents have launched a fundraising campaign for his treatment in the United States which would cost 700,000 pounds.
“Everton Football Club has pledged a donation of 200,000 pounds to support Bradley Lowery in his brave battle,” the club said in a statement on their website.
“We wish Bradley every success and he has the love and support of every Evertonian.”
Everton, who secured a 3-0 win at Sunderland on Monday, host Middlesbrough on Saturday.
