Wycombe have named 46-year-old goalkeeping coach Barry Richardson on the bench for their FA Cup third-round tie against Aston Villa.
Matt Ingram's red card against Morecambe on Saturday means he is suspended for the match, allowing a start for 20-year-old Alex Lynch.
"We've got no one else we can put in there," said boss Gareth Ainsworth. "That's Wycombe, you get your chances."
Richardson last played a professional game for Doncaster in 2005.
In that Football League Trophy match against Cambridge, Richardson suffered a broken leg that has effectively ended his playing career.
Since then, he has been a regular unused substitute for Nottingham Forest, Cheltenham, Peterborough - including being on the bench for their 2011 League One play-off final - and Wycombe.
