Van Gaal down to one center-back as Smalling pulls out injured
Louis van Gaal has confirmed he is down to just one fit center-back for Manchester United's home game against West Ham on Saturday.
Marcos Rojo is the only senior central defender available for Saturday's match, the United manager revealed at his pre-match press conference on Thursday.
Evans suffered a bruised ankle injury in the 5-3 defeat to Leicester and Tyler Blackett is suspended following his dismissal at the King Power stadium.
Chris Smalling was injured in training on Wednesday and will not feature against the Hammers while Phil Jones remains sidelined with a hamstring problem, the United boss said.
Van Gaal said: "All the three right-sided center-halves are out.
"I don't know how long they will be out for. Evans is a very difficult one. His bone is bruised a lot and we have to wait and see, to evaluate it.
"Smalling yesterday ran out of the training session because he had stiff legs. We have to see what that means. But I don't take risks with players."
The injuries to Smalling and Evans have come at a terrible time for Van Gaal, who watched his weak defence crumble to a shock defeat at Leicester last weekend.
The Dutchman, who has won just one of his opening six matches, will have to look for alternatives for the visit of West Ham, who beat Liverpool last weekend.
Midfielders Daley Blind or Darren Fletcher could be used as emergency centre-backs.
Van Gaal is also considering handing 19-year-old Paddy McNair his debut, but denied he would be taking a risk if he drafted any youth players into his starting XI.
"They are always ready, I think," the former Ajax boss said.
"They have hunger to play the game and Manchester United youth education has a certain level that can provide that.
"It's a big difference (between youth football and the Barclays Premier League), but in one game you can show yourself."
