Curtis Jones will miss Liverpool’s Premier League opener at Norwich on Saturday after suffering concussion, manager Jurgen Klopp has said.

The 20-year-old midfielder was forced off after a collision in the first half of Monday’s pre-season friendly against Osasuna at Anfield on Monday.

Klopp told the club’s website: “He had a slight concussion so we just have to follow the protocol. He is fine, he feels fine again, but that’s the protocol.

“He is available for training from Sunday on I think.”

The news comes after left-back Andy Robertson was also ruled out for the first few weeks of the season with an ankle injury sustained in Sunday’s friendly against Athletic Bilbao.
