Having seen midfielder Lucas Leiva pull up against Huddersfield, Liverpool boss Jurgen Klopp does not yet know the extent of his injury.
Liverpool is awaiting further news on Lucas Leiva's hamstring injury after he hobbled out of a friendly win at Huddersfield Town.
The Brazilian had to be withdrawn in the second half at the John Smith's Stadium, with young goalkeeper Shamal George replacing him in the 2-0 victory after boss Jurgen Klopp had used all his outfield substitutes.
Klopp does not yet know the full extent of the issue.
"We have to wait for the exact assessment," he told the media.
