Newcastle United dealt Alexander Isak ‘concern’ ahead of West Ham United clash

Alexander Isak is at risk of missing Newcastle United’s Premier League clash against West Ham this weekend after suffering a “possible concussion”.

The Sweden international had not long come on as a substitute in the Magpies’ Carabao Cup semi-final victory against Southampton last night before being forced off.

The blow to the head followed from James Ward-Prowse’s free-kick. The 23-year-old was checked out by the physios and replaced by Jamaal Lascelles in injury time.

Asked if Isak will be available for Saturday’s fixture versus the Hammers, United head coach Eddie Howe said: “I don’t know.

“He felt a bit groggy taking the ball to his head. I don’t know bad that is, and I don’t know the concussion protocols.”

If a player suffers a concussion, Premier League rules state they should undergo a period of rest from all physical and mental activity - usually for six days - while being monitored closely by the club’s medical staff.

If that is to be the case then that would likely rule Isak out for the visit of David Moyes’ side. However, nothing is confirmed, and Howe will be asked to provide clarity on the situation during Friday’s pre-match press conference.

Newcastle have already suffered a pre-match blow following Bruno Guimaraes’ red card against the Saints. The Brazilian was punished for a late stamp on Samuel Edozie’s ankle - also ruling him out of Bournemouth and Liverpool.

Guimaraes, however, will be back just in time for United’s Carabao Cup final on Sunday, February 26, either against Manchester United or Nottingham Forest.

“I don’t see that being a massive concern for me,” said Howe when asked if players will struggle to concentrate on the Premier League with a cup final on the horizon.

“The concern is Bruno’s red card and Alex’s potential concussion. They’re huge blows for us. We’ll be ready for the next game and the challenges we face before the final but we need our best players.”
