Liverpool have announced that defender Martin Kelly will be unavailable for one month as he recovers from a hamstring tear.
The 20-year-old, who has become a first-team regular since Kenny Dalglish was appointed manager in January, sustained the injury in Sunday's defeat at West Ham.
Kelly was immediately substituted after damaging his hamstring when involved in a sprint with Scott Parker and is now facing a four-week recovery period.
The England Under 21 international will miss Sunday's match against Manchester United, both legs of the Europa League last-16 tie against Braga and the trip to Sunderland on 20th March.
"He'll be out for a number of weeks," first-team coach Steve Clarke told Liverpool's official website.
"It's disappointing for the player because he's been on a good run doing well for us. It's a blow for us but we can handle it and we'll move on."
Liverpool will aim to get back to winning ways without Kelly against bitter rivals United at Anfield after the comprehensive loss at relegation-threatened West Ham.
Fitness and desire
Dalglish admitted after the match at Upton Park that his team deserved to lose and he will be discussing what went wrong with his players at their Melwood training ground.
The Liverpool manager said: "We will sit down and the players can go through the game. We will have a look and make sure we learn from the mistakes that were made.
"We will look to see where we went wrong and try to repair it.
"The pleasing thing was that the fitness and desire to get back in the game was still there. In the last 20 minutes we played well.
"Collectively we will move forward, but we won't dismiss it. We will get back in and see where we are on Tuesday. A week's training will do us no harm at all."
