The England international has managed just two stars in 2017/18, having missed the first three months of the campaign after suffering a hamstring strain during pre-season.
He briefly returned to the fold but this month suffered a leg-muscle tear, ruling him out of this past weekend's FA Cup loss to West Brom.
And Klopp has since confirmed the midfielder will also sit out Tuesday's trip to Huddersfield, while he is doubtful for Sunday's much-anticipated clash against Tottenham at Anfield.
"He [Lallana] is not ready for Huddersfield," said the boss.
"The medical department told me no chance for West Brom, no chance for Huddersfield and a chance for Tottenham.
"After Tottenham for sure, but before Tottenham, I don't know exactly."
