Liverpool flexed their muscles against newly-promoted Norwich in the first game of the season this evening.
Jurgen Klopp's side raced into a 3-0 lead thanks to an own goal and strikes from Mohamed Salah and Virgil van Dijk.
However, Alisson then slipped while taking a goal kick and was unable to continue.
It appeared the Brazilian suffered a problem with his calf and he was replaced by former West Ham keeper Adrian, who signed for the club earlier this week.
But Liverpool supporters were still worried about the rest of the season because of the blow to Alisson.
“There's Liverpool's season over already. Cheers for turning up everyone,” one fan wrote on Twitter.
While another added: “Alisson injured. Off to cry for a bit.
One person wrote: “If alisson is injured long term I will cry no cap.”
And another commented: “Season over if Alisson is badly injured here.”
On the pitch, Liverpool were unmoved by the blow as they added a fourth goal before half-time.
