Liverpool have confirmed that midfielder Curtis Jones will not play against Norwich City on the weekend.
The Reds are preparing for their opening Premier League game of the season, against the newly promoted Canaries at Carrow Road on Saturday.
Manager Jurgen Klopp confirmed that Jones has a concussion, which will keep him out for selection for the coming game.
He sustained the injury during the first half of their preseason game against CA Osasuna.
"He had a slight concussion so we just have to follow the protocol," Klopp told Liverpoolfc.com.
"He is fine, he feels fine again, but that's the protocol.
"He is available for training from Sunday on I think."
"No, not from an injury point of view," Klopp added on any fitness updates for his squad.
"But yeah, a few players had a shorter pre-season than others.
"No, all the others are healthy."
