Big-name signing Adam Lallana will be sidelined for around six weeks after sustaining a knee ligament injury in training in the United States.

"The midfielder...sustained a knock to his lateral collateral ligament during a session at the Reds' Harvard University training base in Boston," a report read on the Reds' official Website.

"Lallana has been assessed by Liverpool's medical staff and does not require surgery."

"No specific timeframe has been placed on a return to fitness, but injuries of this nature can result in a spell of anywhere up to six weeks on the sidelines."

The 26-year-old moved from Southampton this summer for a reported fee of £28million to help the Merseysiders in their return to the Champions League, as well as to maintain their top-four status in the Premier League in the upcoming term.

Lallana's absence will be a big blow for Liverpool, especially after the departure of leading goalscorer Luis Suarez, as the Saints Academy graduate has shown last season that he is not only good at setting up his teammates from the middle of the park, but is also able to find the back of the net himself.
