Liverpool striker Daniel Sturridge has suffered a new injury setback after a foot problem in training ruled him out against Bordeaux in the Europa League.
The 26-year-old was hoping to make a return on Thursday from a knee injury which has kept him out since 4 October.
However, the England international has been sent for a scan after complaining of discomfort in a foot.
"I don't know too much about the situation," said Liverpool manager Jurgen Klopp.
Speaking after Liverpool's 2-1 win over Bordeaux secured the Reds a place in the last 32, Klopp added: "It wasn't a situation I saw because we trained in two groups - the starting line-up and the other players.
"It was really close to the game when the news came. At the moment we have to wait."
Sturridge has made three appearances this season and only 18 in 2015.
His only goals this season came when he scored twice in a 3-2 Premier League home win over Aston Villa on 26 September.
Before Liverpool's Europa League game against Bordeaux on Thursday, manager Jurgen Klopp told BT Sport: "We trained this morning, we were at the hotel and he had to leave to have a scan. We have to wait for the results."

Sturridge, who has 42 goals in 70 Liverpool appearances, joined the Reds from Chelsea in January 2013 and went on to score 28 times for club and country in 2013-14.
Yet he has endured a frustrating time with injuries.
Last season he was out for five months with a thigh injury suffered on England duty. He also had treatment for calf and thigh problems before returning.
And he picked up a hip injury against Manchester United in March, which cut short his season.
That episode led to him visiting medical experts in the United States, and an operation in May, with the former Manchester City player returning to action in September.
But after making three appearances, he suffered a knee injury before Liverpool's draw at Tottenham on 17 October.
