Crewe striker Calvin Zola is a major doubt for the clash with Swindon on Saturday afternoon but midfielder James Bailey is in contention.Both were forced off during last weekend's 1-0 defeat at Cheltenham after an accidental collision with Town striker Drissa Diallo left the pair floored.

While Bailey, who suffered a cut above the eye in the incident, has recovered in time to feature, Zola is likely to miss out due to his head injury.

Goalkeeper Adam Legzdins (shoulder) and midfielder Jake Livermore (fractured fibula) are still missing through injury and neither are expected back until late December.

Last Saturday's defeat left Alex six points adrift at the bottom and they will be in search of only their third league win of the season when the Robins visit Gresty Road.
