Crewe's Jon Guthrie is set for surgery on a hernia injury.
The defender has continued to play through the pain barrier over a number of weeks.
After being forced off at half-time against Stevenage at the weekend, he is now set to go under the knife to repair the damage.
Crewe boss David Artell told the club's official website: “Jon needs an operation. He has been playing with a hernia over the last few weeks and he played for as long as he could.
"He cannot go on any longer and he will have an operation on Friday."
