The incident leading to the injury, saw Canvey's Jeff Minton go in hard with what has been described as a "clumsey tackle" on David who was taken to the ground instantly.
The match was stopped for almost ten minutes while he received treatment from Shots physio Sue Bowen and the Canvey Island Football Club doctor. He was then stretcherd off and taken to Southend Hospital where he underwent surgery during the night.
He is expected to stay in the hospital for several days and it could be months before he is fit enough to even think about training again.
Everyone at Shots Mad offer David their best wishes for a speedy recovery and if you wish to send him a message of support, please email your message to Shotsweb at: shotsweb@yahoo.co.uk and they will pass them on for you.
