Liverpool goalkeeper Loris Karius has undergone a successful operation to repair his broken right hand.
The German returned home early from the club's tour of the United States after sustaining the injury having collided with team-mate Dejan Lovren in Wednesday's 1-0 defeat to Chelsea in the International Champions Cup.
Karius, a £4.7m signing from Mainz this summer, is likely to be sidelined for eight to 10 weeks, dealing a blow to his hopes of challenging Simon Mignolet to be manager Jurgen Klopp's first choice.
"I'm back at home after a successful surgery! Thank you guys for all your get-well wishes!" Karius wrote after tweeting a picture of his bandaged hand.
Karius turned down a place in Germany's Olympic squad in order to fight for a starting berth but injury now means fellow new signing Alex Manninger, a 39-year-old veteran who arrived from Augsburg on a free transfer, will now deputise for Mignolet for the start of the campaign.
The remainder of the squad returned home on Tuesday immediately after their 2-1 defeat to Roma to begin preparations later this week for their final International Champions Cup match against Barcelona at Wembley on Saturday, which is live on Sky Sports 1.
Liverpool start their Premier League campaign at Arsenal on August 14, also live on Sky Sports 1.
