Rotherham United manager Mark Robins is unsure when defender Marc Joseph will be ready for a first-team return.
The 31-year-old former Hull City player has been sidelined since last month's Carling Cup clash at Sheffield Wednesday with a neck problem.
"Marc still has some pain in his neck," said Robins. "He had a scan and it showed a disc problem in the neck.
"He does everything in training except head the ball and still has some pain and must wait for that to cease. We're being cautious.
"We won't be rushing things and I'm not sure how long he'll remain out but hopefully it won't be much longer."
