Charlton supporter and Valley Gold member Stuart McRae could scoop £10,500 when he takes on the Valley Gold Crossbar Challenge at half-time on Saturday.
The rollover jackpot for the competition, which launched in September 2016, started at just £500 but has now grown to over 20 times that after no fans were able to hit the crossbar last season.
Supporter Stuart visited the club’s training ground last week to meet U23s boss Jason Euell and some of his squad to get some tips on hitting the bar.
The Crossbar Challenge takes place every home, league matchday and its jackpot rolls over by £500 every time it is not hit.
The competition is open to all Valley Gold members, who are automatically entered into the draw to take part, and also supporters that purchase jackpot tickets.
Fans that buy jackpot tickets should write their contact details on the reverse of their unsuccessful jackpot tickets and place them in the Valley Gold letter boxes, which are dotted around The Valley, to enter.
