London: Liverpool suffered a blow on the eve of the new Premier League season as Wales midfielder Joe Allen was ruled out for up to four weeks with a hamstring injury.
Allen suffered the problem in the early stages of Liverpool`s friendly against Swindon last weekend and he was eventually forced to limp off.
Liverpool manager Brendan Rodgers, speaking at Friday`s press conference ahead of his side`s league opener at Stoke on Sunday, said: "He will probably miss three to four weeks, which is disappointing.
"He certainly won`t be available for the weekend."
There was better news for Rodgers about Liverpool and England striker Daniel Sturridge, who is on course to make his comeback from a hip injury in early September.
Sturridge continues to recover following an operation in Boston to rectify the long-standing hip problem.
He made only 18 appearances last season as he struggled with a succession of injury concerns, with his last appearance coming in FA Cup win at Blackburn in April.
But this week he posted a video of him running and kicking and heading a ball on social media with the message "Closer...".
"Daniel will hopefully be back towards the beginning of September - he`s working very hard," Rodgers said when asked for a Sturridge fitness update.
