Chelsea forward picks up knee problem
Ben Sahar could be facing a lengthy spell on the sidelines after picking up a knee problem.
He suffered the injury after half an hour of De Graafschap's Dutch Cup defeat to FC Twente on Wednesday evening.
Chelsea striker Sahar joined Eredivisie side De Graafschap on a six-month loan deal in January.
He will not learn the extent of the injury until he has undergone a series of tests but De Graafschap coach Darije Kalezic fears it will be bad news.
"We have to wait and see how serious it all is," he said. "But I must say it didn't look good."
