Sheffield United have been dealt a double blow with news of injuries to Neill Collins and Shaun Miller.
Both players were substituted in the Boxing Day win over Scunthorpe before the full extent of their problems was announced on Friday.
Collins has suffered a triple fracture to his cheekbone and will be out for up to two months, while Miller is likely to miss the rest of the season with cruciate ligament damage.
"Neill looks set to be sidelined for anything from four to eight weeks," manager Danny Wilson told the club's official website.
"He was operated on straight after the game on Wednesday and he won't be able to train for a while."
He added: "It is more bad news with Shaun. It looks like we have lost him for the season. He has damaged his cruciate ligaments and will be missing for around seven to nine months.
"It is especially frustrating for the two lads, who are both at the top of their games, Shaun in particular. He has been in excellent form and has worked so hard to nail down this opportunity since arriving in the summer."
