Wycombe boss Gareth Ainsworth is "100% sure" he will have enough players fit to fulfil Monday's FA Cup fourth-round tie with Tottenham (19:45 GMT).
"Tomorrow [Saturday] is the FA round of testing for us. We have to fulfil that," Ainsworth said.
"Out of 30 players I think I will have high-20s."
Championship club Wycombe almost knocked Spurs out of the FA Cup at the same stage in 2017, when as a League Two club they were leading 3-2 at White Hart Lane until the 89th minute.
However, late goals from Dele Alli and Son Heung-min rescued Tottenham.
