The goalkeeper suffered the injury while on international duty with Scotland a fortnight ago, and although he missed their game against Northern Ireland, he did manage to play for the Black Cats' in the 2-1 defeat to Spurs days later.
However, manager Steve Bruce claims the problem hasn't totally cleared up despite an extended break from action as a result of their FA Cup third round exit.
Bruce doesn't want to use Gordon if he is not right, as he believes at least four of the nine goals his side have conceded in their last three games have been down to the Scot.
Sunderland boss said: "Craig has a sore knee which flared up after he came back from Scotland and it will not go away, so Simon has a chance tomorrow.
"We conceded three at Stoke and Craig knows he should have done better there.
"His confidence has taken a knock since then.
"When Craig is good, he is very good, but he is having a bit of a wobble at the moment.
"Simon sniffs a chance and the kid has been fantastic in training."
Steed Malbranque is likely to miss out in midfield with Ahmed Elmohamady in line to return, but Bruce will be without Michael Turner (knee), Fraizer Campbell, Lee Cattermole and Danny Welbeck.
The Black Cats head to Goodison Park seeking their first win there since 1996.
