The England forward spent 10 days in Los Angeles to help with his recovery and he will now link up with the medical team at the Boston Red Sox, who share the same owners as Liverpool in Fenway Sports Group.
Sturridge will be accompanied by Liverpool’s head of conditioning Glen Driscoll, in the hope Red Sox specialists may be able to assist in ending the striker’s persistent thigh problem.
The 25-year-old has not played since August 31 after straining a thigh while training on international duty with England. On the eve of his club comeback he pulled a calf muscle in training with the first team and just when he appeared to have got over that, he sustained another, different, thigh injury which has ruled him out until the new year.
Rodgers said last month the club may have to look even deeper into the root of Sturridge’s problems, of which this is the ninth separate but similar injury of his career. The player suggested the issue may be hereditary as his father, a trainee at Birmingham, and two uncles Dean and Simon — both professional players — suffered the same issue.
While Sturridge remains on schedule to return in the new year, fellow striker Mario Balotelli is still trying to overcome the groin injury he sustained on international duty just over a month ago. The Italy forward made his comeback as a second-half substitute in Sunday’s defeat at Manchester United but didn’t travel with the squad for last night’s Capital One Cup quarter-final at Bournemouth.
Instead he has stayed behind to receive further treatment on the injury with a view to him being fit for Sunday’s visit of Arsenal.
Defender Glen Johnson is out for a month with a groin injury suffered at Old Trafford, meaning on-loan Javier Manquillo could get an extended run if manager Brendan Rodgers reverts to a flat back four, having experimented with three centre-backs against United.
