Liverpool goalkeeper Alisson exited the club’s match against Norwich City on Friday after an apparent leg injury.
The Brazil international came off in the 39th minute of the Premier League season opener after slipping and holding his right calf. He waived off the stretcher but needed assistance from the team’s trainers to come off the pitch at Anfield.
Newly signed Spanish goalkeeper Adrian came on for the Reds, his first game in uniform since joining from West Ham on a free transfer this week.
Liverpool sold longtime keeper Simon Mignolet last week to Belgian side Club Brugge.
Alisson was instrumental in Liverpool’s Champions League title run in May, as well as Brazil’s Copa America victory this summer.
