Crewe's on-loan Manchester City forward Harry Bunn has suffered knee ligament damage. The 19-year-old suffered an awkward fall in the second half of Saturday's 0-0 draw against Tranmere.
Crewe boss Steve Davis said: "He's been with the consultant over in Manchester and has found out that he's got some extensive ligament damage - his lateral ligament and his cruciate ligament.
"So he's going to need a couple of operations to put that right and obviously an extensive rehabilitation period depending on how well that goes. It could be the season to be honest.
"We're just disappointed for him. He's a lovely lad, he came here to get some games and was enjoying his football."
