Liverpool boss Klopp revealed Henderson, along with three other team-mates, was nowhere near coming back to full intensity on the training pitch.
Gareth Southgate‘s England kick off their first Euros match against Croatia on June 13 – in less than six weeks – but the German gave a negative update on Henderson and fellow long-term absentees Virgil van Dijk, Joe Gomez and Joel Matip.
Liverpool captain Jordan Henderson is still likely to miss England’s Euro 2020 tournament
The midfielder and Reds captain, 30, has been out since undergoing groin surgery in February
He said: ‘There are a lot of steps to go before they can take part in football training. They are all quite a long way from that.
‘Nobody has told me ‘fasten your seat belt they will be team training next week’. When players start running during rehabilitation it is in straight lines only at first.’
The Reds’ final match of the campaign is against Crystal Palace at Anfield on May 23, the day before Southgate is set to announce his squad for the tournament, but the central midfielder’s prospects of featuring in that game are slim to non-existent.
And boss Jurgen Klopp admitted he was still a ‘long way off’ returning to full-intensity training
Liverpool skipper Henderson, 30, is still recovering after groin surgery in February and his likely absence will prove a major blow to the Three Lions’ chances.
Klopp’s side were knocked out of the Champions League by Real Madrid last month and are not in any cup competitions, meaning they are relying on a top-four Premier League finish to qualify for next season’s Champions League.
Next up they travel to Manchester United on Sunday, four points behind fourth-placed Chelsea and one behind fifth-placed West Ham, with Tottenham and Everton hot on their heels.
