The Sunderland manager, Simon Grayson, has paid tribute to Bradley Lowery - ahead of tonight's League Cup match at Everton.
Both clubs will wear logos promoting the Bradley Lowery Foundation instead of their usual shirt sponsors, to promote the charity set up in memory of the 6-year-old from Blackhall, County Durham.
Sunderland’s red and white striped shirts will sport the logo of the newly-formed foundation, with the club’s principal sponsor Dafabet donating the prime space in order to support the charity.
The one-off shirts will then be signed by the players after the game and auctioned by the charity to raise funds.
Bradley formed a close bond with Everton FC, and that club has also been a supporter of the Lowery family.
Bradley led out the Everton team at their game with Manchester City in January.
The club also pledge £200,000 towards Bradley's treatment for neuroblastoma - a disease which took the little boy's life in July.
After Bradley’s death, his family set up the Bradley Lowery Foundation.
The charity will offer grants and other forms of support to families going through similar situations.
Tonight's match, at Goodison Park, will kick off 7.45pm.
