Liverpool will be without Naby Keita for Saturday's trip to Huddersfield Town, but Virgil van Dijk will be available.
Keita injured his hamstring playing for Guinea during the week, while van Dijk returned prematurely to Anfield due to a rib injury.
"We have yesterday's session and a few of the boys trained, we have to see how they react after that," he said. "It's pretty sure Naby will not be.
"With all the rest, we have to see how it develops."
On Van Dijk, Klopp added: "Football players play very often with some kind of pain. He has no problems with that (his ribs) any more."
