Evans named an unchanged side for Sunday evening’s Championship game against Nottingham Forest away from home at the City Ground.
Speaking to Leeds’s official Twitter account just before kickoff, the Scot said: “The only thing I can tell the supporters regardless of the result and the performance today, it cannot be the same XI that goes out there on Tuesday and it won’t be the same system of play. So there will be changes on Tuesday, yes.”
Leeds failed to make it three wins in a row in the Championship on Sunday evening, as they played out a 1-1 draw with Forest.
Nelson Oliveira took advantage of a mix-up in the Whites’ defence to put the home team in the lead in the 17th minute.
The West Yorkshire outfit, though, staged a comeback and equalised in the 80th minute through a low strike from Sam Byram.
Speaking after the match on BBC Radio 5 live 606 on Sunday evening, Evans said that Middlesbrough and Brighton & Hove Albion will not be happy with the fixture schedule.
“The unhappy people in that are the coaches of Middlesbrough and the coaches of Brighton,” said the former Rotherham United boss. “They are not happy that Derby are going to Leeds, who have just played on Sunday night on the telly.”
Derby, Middlesbrough and Brighton are all aiming to finish in the top two of the Championship table this season and get automatic promotion to the Premier League.
The Rams were in action on Boxing Day and will face Leeds at Elland Road on Tuesday evening.
Middlesbrough’s game against Blackburn Rovers at Ewood Park on Boxing Day was postponed, and Aitor Karanka’s are in action this evening.
Brighton played on Boxing Day and will return to league action on Tuesday evening.
