Brendan Rodgers suggested in a pre-match interview for the game against Sunderland that Joe Allen could return to full training in time for the game against Chelsea in the League Cup.
The Liverpool squad departed for the North East on Friday afternoon, but left the Welsh international behind as he continues to nurse an injury that has hampered him all season.
The former Swansea City man has played a big part for The Reds this season, making 15 appearances overall, but has been missing from action since the game against Manchester United in mid-December due to injury.
Earlier this week, it was announced the 24-year-old was back doing light training and had been touted with a potential return for the game this weekend. However, Rodgers confirmed to the press that it wasn't to be.
"Joe is working outside now and hopefully over the course of the next week or so he will be ready to rejoin the group," Rodgers was quoted on Liverpoolfc.com
"He's had an issue with his knee for most of the season. He came back well initially but it's been a niggling injury for him. He came on in the game away to Leicester and hurt it again in a tackle.
"We want to make sure that when he comes back he's right, rather than still feeling the effects which then hinders his performance."
Nevertheless, the news that he could return to full training at some point in the next week could give the Northern Irish manager the boost he needs when heading into the League Cup Semi-Final against Chelsea.
The deep-lying midfielder has proven to be one of the tidiest footballers in the Premier League when it comes to distributing the ball, which will be a vital trait Liverpool will need heading into the first leg of the semi-final tie.
Liverpool are currently facing a season defining month where they could easily turn their fortunes around, but just as easily make matters worse, as a League Cup final, FA Cup fifth round and nine Premier League points are up for grabs.
