Charlton have donated a shirt to the 'Shirts for Jordan' campaign which is looking for as many football shirts as possible from all levels of the footballing pyramid. The shirts will be displayed at Sinnott's funeral before being donated to Sport Relief.
Charlton's kit man Wayne Baldacchino explained how he was made aware of the cause.
"I saw the news where the player got attacked. Obviously, just seeing that is horrible just in general not just through football. But then a couple of days later I had a couple of the first team boys asking 'could we send in a shirt as condolence because every league club is going to do it'."
The tragedy has seen a fantastic outpour of support from clubs up and down the football ladder and up and down the country with teams from the Premier League right the way down to Amatuer teams sending in their shirts.
"Some of his ex-team mates or ex-Football League players have requested that every club has a shirt with his name and number so they can have that at the funeral procession. Almost as a football family kind of scenario.
"Once the burial has taken place, they're going to use these football shirts from all the clubs for sport relief, so that’s almost like he’s leaving a legacy."
Wayne went on to explain how once again the footballing community has come together under difficult circumstances to help bring something positive from a sad scenario.
"As heartbreaking as his loss is to the football world, the football family stick together when anybody within football has any kind of tragedy, so all of those shirts will be going to sport relief and raising funds in his memory, so he’s sort of leaving a legacy through that. But obviously as a club, Charlton Athletic, we need to do our bit, which is why Josh Cullen, Chris Solly, Jake Forster-Caskey and Johnnie Jackson did this shirt quite soon after it hit the news."
