Chesterfield full-back Dan Jones has suffered a bizarre ankle fracture that was the result of "pushing and turning at the same time".
Jones suffered the setback in the Spireites' 4-0 League One defeat to Swindon, sustaining the break despite not coming under any strong challenge.
Chesterfield have confirmed the left-back could now face a six-month lay-off.
"On Saturday when I ran on to the field Dan immediately told me that he had heard something pop, which is never a good sign," said Chesterfield's head of sports science and medicine Rodger Wylde.
"He was pushing and turning at the same time. You might think that couldn't cause a fracture, but whenever you have strong enough forces going through at the wrong time you can cause damage, even a fracture."
Specialists are yet to determine whether he must undergo surgery, and Wylde added: "He's going to see an ankle specialist tonight (Monday).
"Then we'll know how the injury should be treated and whether he'll need to be operated on.
"With a lower limb injury like this you're looking at 12 weeks for the fracture site to fuse together and possibly then another 12 weeks for consolidation, but we'll know more after seeing the specialist."
