Liverpool midfielder Jonjo Shelvey has been ruled out for the next three months with a knee tendon injury.
The 18-year-old withdrew from England Under-19's friendly against Germany on Tuesday and further assessment at the club's Melwood training ground has revealed it is a significant problem.
"I'm a bit down at the moment but I'm just hoping now I can come back stronger," Shelvey told liverpoolfc.tv. "I am now going to take a 12-week rehabilitation and hopefully I'll be back soon."
Shelvey has become a regular among the substitutes since Dalglish took over last month and is clearly rated by his manager, who brought him on in all of his first six matches in charge since taking over from Roy Hodgson on January 8.
Dalglish said of the teenager, signed from Charlton towards the end of last season: "He has done well so it is a disappointment for everyone."
