Crewe midfielder Eugen Bopp looks likely to miss the rest of the season through injury.
Bopp has been struggling with an ankle problem for some time with his last appearance coming against Hartlepool in late December.
The 25-year-old has travelled to Germany to see a specialist over the injury and Alex assistant manager Neil Baker does not expect Bopp to feature for the remainder of the campaign.
"It's unfortunate for Eugen as he just can't seem to shake off the niggle," said Baker.
"He is seeing an ankle man in Germany and we will see what happens, but we only have six games left."
