Young fan set to lead the team out on Sunday
Harvey is no stranger to manager Neil Harris, the players and Lions supporters as Millwall FC were a driving force in supporting the campaign to ensure Harvey and 77 other children in the UK got the vital medication Vimizim they need funded by NHS England for Morquio sufferers.
An online petition was signed by over 10,00 people with the club also joining Harvey, and his school Surrey Square Primary in delivering letters supporting his campaign to No.10 Downing Street - and it worked with the green light for funding given in late November.
Harvey, who lives just around the corner from the stadium, has been a visitor to the training ground with Mum Vikki and Dad Dean, and a mascot at The Den this season. He was also visited by striker Aiden O'Brien in February as a surprise for his birthday.
At the time Aiden joked to Harvey that if we got to Wembley, the club would 'sort something out' - not knowing that initial discussions had taken place long before Christmas.
An emotional Vikki said: "Even though we knew this was a possibility some months ago, we put it to the back of our mind and didn't want to tempt fate.
"The club have been marvellous to us as a family right the way through and this caps it all. It is an unbelievable gesture and one that we, and Harvey, will never forget."
Lions boss Neil Harris added: "It was an absolute no-brainer from our point of view. The lads have really taken a shine to Harvey from the first time he came to the training ground with his fantastic smile and positive attitude.
"He has the real heart of a lion and we are honoured to have him as our mascot on Sunday."
