A woman believed to be Eriksen's wife made her way onto the pitch.
The Guardian said: "On the BBC, they’ve cut back to the studio and probably not before time. Gary Lineker, Cesc Fabregas, Alex Scott and Micah Richards all look in total shock, as am I. It’s difficult to know what to type here, really. Please God, Christian will be OK."
The players have retiurned to their dressing rooms.
The Independent said: "The medical staff are still working on Christian Eriksen. Sheets are being held up around the player as they continue their work.
"The stadium is in total shock. Some of the Danish players are in tears. There’s no word yet on Eriksen’s condition. The television camera’s are avoiding that area of the pitch."
