Liverpool striker Daniel Sturridge has suffered another injury setback after breaking down training with his club side on Tuesday.
Sturridge limped out of a practice session amid fears that he has suffered a new thigh injury, sources have told ESPN FC.
The England forward is set to have a scan in order to assess how serious the problem is and how long he will be out for.
He had been set to make his comeback for the Reds in Sunday's Premier League match at Crystal Palace, having not played for his club since the end of August.
Sturridge has not featured in any game since playing 89 minutes for England in a 1-0 friendly win over Norway on Sep. 3.
He suffered a thigh injury during an England practice session two days later, leading manager Brendan Rodgers to claim that national team boss Roy Hodgson had been over-training the player.
Sturridge was close to a comeback when he suffered a calf injury while training with his club on Oct. 16.
In his absence, Liverpool have failed to find the form that carried them to a runners-up finish in last season's Premier League.
Rodgers' side have slumped to 11th place and are facing a group-stage elimination from the Champions League, having won just five out of the 14 matches that Sturridge has missed across all competitions.
The 25-year-old announced on Twitter last Wednesday that he had returned to full training, hinting that he was close to being ready to play again.
But his latest setback is a major blow to Rodgers, whose side have managed only 14 goals in 11 league games this season -- half as many as leaders Chelsea.
None of his other recognised strikers -- Mario Balotelli, Rickie Lambert and Fabio Borini -- have scored a league goal this season.
Rodgers faces the prospect of asking Balotelli, who has struggled for form since a 16 million pounds move from AC Milan in August, to lead the attack against Palace.
