Steven Gerrard is embracing his rehabilitation process from a hamstring injury with great determination, according to Liverpool manager Roy Hodgson. Gerrard will be missing for up to a month after suffering the injury in England's defeat by France last week. "He's straight into it and he's anxious to get back as quickly as possible," said Hodgson. "He's not letting any dust settle but I don't think there's so much he can do at the moment." He added: "First of all he has to let the injury quieten down and then really start to work on it." Hodgson has also hailed the work being carried out by Liverpool's new medical team. The sports science and sports medicine staff recruited in the summer have introduced pre-training exercises designed to prevent pulls and strains. Only Gerrard (hamstring), Jay Spearing (ankle) and Daniel Agger (calf) occupy the treatment room. Hodgson told Liverpoolfc.tv: "You've got to pay credit to the medical team. With Steven the muscle injury was not one provoked by us. "Daniel's is an unusual injury which could have come at any time and Jay Spearing was unfortunate in that he fell awkwardly - that could have happened at any time. "Credit to the players - they're buying into the ideas and all the work we do to prevent injuries at the start of every day."
