The central midfielder has revealed he is ready to come back to first team action.
Eustace said: "I will be able to play on saturday but I may be on the bench, I will hopefully play the full game against Coventry on december the 11th.
He went on to say: "My groin has held up, I still feel nervous but it's now or never as I want to help the side get back to winning."
However, Tony Pulis is reported to believe that John needs longer to recover but will go along with John's own verdict.
