Everton goalkeeper Jordan Pickford escaped action over this challenge on Liverpool defender Virgil van Dijk during the Merseyside derby.
Reds manager Jurgen Klopp has revealed that van Dijk's knee injury is “not good”.
The Netherlands defender, 29, was hurt in a rash challenge by Pickford in the first half of Saturday's 2-2 draw.
Van Dijk could not continue and will see a specialist on Sunday (today) to discover the extent of the injury.
“Virgil played I don't know how many games in a row, he plays with pain, but he couldn't play on,” said Klopp.
“That's not good.”
Liverpool's claims for a penalty from the incident were turned down as Van Dijk was ruled to be offside before England number one Pickford clattered into him.
“It was a clear penalty I saw and then we saw the flag went up. I thought they would still look at the foul but that didn't happen,” said Klopp.
“I don't want to say Jordan Pickford wanted to do it but it is not a challenge a goalie can do in the box.”

Meanwhile, Thiago went for a scan along with Van Dijk and, while the club are hopeful his injury is not serious, they will see how it settles.
