Jurgen Klopp has provided an explanation on what happened to Dejan Lovren in Liverpool's warm-up ahead of their 3-0 win over Huddersfield.
The Croatian centre-back was meant to start the Premier League fixture, and was training on the pitch alongside his Reds teammates at Anfield.
But moments later it was announced that Lovren would not be playing any part of the fixture after picking up an injury.
Ragnar Klavan was announced as the Croatian's replacement, and went on to play the entire game, which Liverpool won 3-0.
Speaking about what happened to the defender, Klopp told Liverpool's official website: "It was the last pass. Maybe you saw it.
"Joel [Matip] and Dejan were exchanging passes and then in the last one, he felt something in the muscle.
"I don't know exactly, we had no time – the only question I asked in the treatment room was, 'Yes or no?' and I got a no and then we changed. It is his thigh."
It wasn't clear whether Lovren would feature for the Reds this weekend after his poor performance in the 4-1 defeat to Tottenham.
The centre-back was at fault for Spurs' first two goals, and was replaced by Klopp after the half hour mark.
But he got the nod for Saturday's fixture, before picking up an injury.
