LIVERPOOL -- Jurgen Klopp said defender Dejan Lovren was substituted at half-time in Sunday's 2-2 draw with West Ham United at Anfield as a precaution.
Lovren was replaced by Ragnar Klavan after complaining of cramp, with Klopp saying he could not risk putting the centre-back out for the second half.
"He said he had a cramp," Klopp told a news conference. "In the ear of the medical department this is a hamstring issue -- it was in that region.
"Dejan wanted to carry on, but we cannot take the risk in this situation. Hopefully, we took him [off] early enough.
