FEYENOORD have been rocked by an injury crisis ahead of this week's Europa League clash against Rangers with on-loan Roma full back Rick Karsdorp out and main striker Nicolai Jorgensen extremely doubtful.

The Ibrox side travel to Rotterdam hoping to take a step closer to qualifying for the knockout stages of the competition.

And their task has been made easier after former Rangers boss Dick Advocaat revealed two of his key players almost certainly won't play.

Dutch international right back Karsdorp, who cost Roma £15 million before being loaned back to Feyenoord, has a calf injury.

And Danish hitman Jorgensen is looking unlikely to make it after injuring a thigh in training.

Advocaat said: "Rick Karsdorp is out for two weeks and won't play against Rangers.

"And Nicolai suffered an injury in training. He's a real doubt for this week's game. We won't know until the day before.

"And I would rather give players a chance to rest properly anyway.

"I want them to be fully fit when they return, not constantly checking if they are fit or not."

Feyenoord also have a doubt over another full back, Ridgeciano Haps, who missed their weekend draw at Groningen.
