Leeds United have suffered an injury blow ahead of Wednesday night's match with Liverpool at Anfield in the Premier League.
Robin Koch suffered a head injury in their 4-2 defeat to Manchester United on Sunday afternoon and has now been ruled out of the match at Anfield.
It is a significant blow for Leeds as the midfielder was filling in the role that the sidelined Kalvin Phillips usually occupies.
In a statement today, the club said: "Leeds United can confirm that following a clash of heads, Robin Koch passed all of the on-field concussion screening tests that are currently part of the Premier League protocols.

"The player was told if he developed any symptoms he should sit down on the field of play and would be substituted immediately, which is what Robin did in the 29th minute of the game [against United].
"The medical staff at Leeds United have always been in favour of temporary substitutions for head injuries, as it would allow the staff more time to assess an injury and allow a period for symptoms to potentially develop.
"Robin will follow the concussion protocols before returning to play."
Leeds had come in for criticism over how the incident was handled - with others also questioning the current protocols, and many backing renewed calls to introduce temporary substitutions for head injuries.
Liverpool against Leeds is a 7.45pm kick off on Wednesday evening at Anfield.
This match was originally due to take place on Boxing Day, but was postponed at the request of Leeds; who had a shortage of players after a Covid-19 outbreak at the club.
A win for Liverpool will move them to within three points of Premier League leaders Manchester City.
