Joe Gomez is expected to be out for up to six weeks after it was confirmed he suffered a fractured leg during Liverpool’s 3-1 win over Burnley on Wednesday.
The England defender was hurt in the first half of the Premier League fixture following a tackle from Ben Mee and had to be substituted in the 23rd minute at Turf Moor.
Gomez, who ended up sliding into an advertising board following the initial contact, received treatment by the pitch before being carried away on a stretcher.
Liverpool’s boss had aired his frustration at Burnley’s physical approach after his team’s victory on the road, suggesting referee Stuart Attwell had failed to control the game on a wet night in the north west.
“The challenges from the beginning on the wet ground, the referee should have said something earlier,” Klopp told BBC Sport. “I told him if you don’t say ‘be careful’ they will keep going until something happens.
“The injury threat is hard, the first few challenges everyone likes and it is a part of football but it leads to the situation, no foul, what can I do, but Joe Gomez is injured.”
