Jordan Henderson suffered a serious knee injury during Liverpool’s 1-1 draw against Borussia Dortmund on Thursday night, according to Jurgen Klopp.

The Merseysiders’ manager delivered a pessimistic verdict on Henderson in the wake of his team’s captivating Europa League quarter-final first leg clash in Germany.

The Liverpool skipper was withdrawn at half-time, when his team had a 1-0 advantage, and replaced by fellow midfielder Joe Allen.

Speaking to BT Sport Europe immediately after the match, Klopp said: “It’s a disappointment with Hendo, it’s a knee injury – not too good, so that’s bad news.”

Henderson is now a major doubt for Liverpool’s clashes against Stoke in the Premier League on Sunday and next Thursday’s return leg against Dortmund at Anfield.

He is set to have a scan on his knee on Friday to assess the full nature of the injury.

It was the only downbeat note of an otherwise uplifting night for Liverpool, who produced an outstanding defensive display against one of Europe’s in-form teams.

Divock Origi, who had been preferred up front to Daniel Sturridge, put the visitors 1-0 up in the first half with a crucial away goal before Mats Hummels equalised early in the second period.

The latest Liverpool news is that pundits Gary Lineker and Stan Collymore were among those hailing the team’s performance in the immediate wake of the 1-1 draw.
