The 29-year-old Black Cats frontman has donated £2,690 to a fund set up to raise funds to cover the cost of an operation for Gateshead midfielder JJ O'Donnell, who is suffering from the rare foot condition sesamoiditis.
O'Donnell confirmed the news via his Twitter account, tweeting: "I'm not singling Danny out as without everybody donating, I wouldn't have ever reached my target, but a donation like that has left me speechless.
"I've never met Danny, but for him to put an astronomical amount like that towards a fund of a lad who he doesn't know speaks volumes of what a true gentleman he is.
"Premier League players take a lot of stick about being role models, but this shows just how much of a role model someone can be.
"I'm truly humbled and forever thankful
Hopefully I'm able to meet Danny and thank him personally for an incredible thing to do."
Supporters of the Tyneside club, which plays in the Vanarama Conference, initially set out to raise £5,000, but Graham's contribution has boosted the total to in excess of £7,000, around the full cost of the treatment.
