Daniel Lafferty, the Northern Ireland international, is set to return to Sheffield United's line-up for tomorrow night's game at Millwall.
Lafferty was an unused substitute for his country's victory over Norway last night and trained with his Blades teammates this morning, after reporting no after-effects of the trip to Belfast.
And Wilder, whose side can go further ahead of promotion rivals Bolton and Fleetwood with victory over Neil Harris' side at Bramall Lane, said this morning at his pre-match press conference: "Daniel is back with us, he trained this morning.
"He was an unused substitute for his country so he'll have done some work over the weekend with his national side. He's back with us now and available for selection."
Caolan Lavery went for a scan on the knee injury he picked up in Saturday's draw at Oldham, but Matty Done was described by Wilder as "fine" after coming off with concussion.
"We've got to plot our way through this period and Caolan has played an important part so far, either starting or coming off the bench," Wilder added.
"Obviously it's a disappointment that he'll miss out on Tuesday. He's an important player for us. But we can cope."
