Daniel Agger out for 'a few weeks' with rib injury - Kenny Dalglish<br /><br />Liverpool defender Daniel Agger will be out for "a few weeks" after fracturing his rib during Sunday's Carling Cup final victory over Cardiff City.<br />Reds boss Kenny Dalglish confirmed the injury to the club's official website and Agger is now certain to miss Saturday's league match with Arsenal.<br />Liverpool are also yet to discover if a tight hamstring will sideline captain Steven Gerrard for the game at Anfield.<br />Gerrard limped out of England's 3-2 loss to the Netherlands on Wednesday.<br /><br />"If I don't know what it is, I can't tell you whether there is every chance or no chance [of Gerrard facing Arsenal]," Dalglish told Liverpool's official club website. "It's best for us to just wait and see what the medical people have to say once they've seen him."<br />Agger's latest problem adds to the long list of injuries the Denmark international has suffered since his move from Brondby in 2006.<br />Last season alone, serious calf and knee tendon problems meant he featured in just 16 top-flight matches.<br />Agger, 27, and centre-back partner Martin Skrtel have helped Liverpool to the second-best defensive record in the Premier League this season, with the club conceding just 23 goals in 25 matches.<br />"Anybody that is injured is a miss. Daniel has been playing fantastically well this year, but we'll miss anybody that is not fit and available," said Dalglish.<br />"The squad is there to cover eventualities, injuries and suspensions and we'll need to cover for Daniel if he's going to be out for a few weeks."<br /><br />/football on Youtube brings you the latest football news, transfer rumours and footballing gossip from the English Premier League and European Champions League.
