The injury occurred when the Portugal international clattered into Gunners goalkeeper Aaron Ramsdale. Jota was substituted 76 minutes into the match.
Jota is an important player for Liverpool. The striker has scored 19 goals in 45 appearances for the Reds.
Therefore, hopefully the knock that Jota picked up last weekend is nothing too serious.
