Isak, who had been on for only 11 minutes after appearing as a half-time substitute, had to be helped off the pitch in what reports have deemed to be a fractured leg.
Scans are expected to assess the extent of Isak’s injury, which will leave the Swedish international out of action for a number of weeks if a fracture is confirmed.
However, reports have stated that manager Arne Slot will welcome the return of Danns sooner than expected, which will give him another option in attack.
This Is Anfield report that the 19-year-old is now back working on grass again, and he is due to make a full comeback within the next two weeks.
Early January is his projected target to return to the pitch and as Liverpool prepare to clash with Leeds, Fulham and Arsenal next month, he may have come back at the right time.
The Reds also host League One side Barnsley in the third round of the FA Cup on January 12th in a game where Slot could give Danns a run in the first team since the 2-1 win over Southampton in the Carabao Cup.
