The young defender sustained the injury during the Reds' 3-0 victory over Hertha BSC at the Olympiastadion on Saturday.
And he will be not be risked during Tuesday's meeting with Bayern Munich, or the clash with either Atletico Madrid or Napoli the following day as a result.

"But we will take no risk with him."
