Millwall supporters have raised £2,800 for the Bradley Lowery Foundation.
The sum, presented to the Black Cats at half-time of Saturday's 2-2 draw with Sunderland, formed part of the launch of 'For Bradley', a campaign set up to raise money to create a holiday home for sick children and their families.
'For Bradley' has captured the hearts of the football and wider sporting community, with thousands of messages of support being received about the campaign.
Both Sunderland and Millwall warmed-up in special 'For Bradley' t-shirts, whilst a special matchday programme was commissioned and pin badges were worn.
Fans are encouraged to share pictures on social media of their 'thumbs up #ForBradley', with clubs at all levels of the game becoming involved.
