Cook, who bagged Walsall's equalising goal during Saturday afternoon's clash, will be suspended for the trip to the North East with the Saddlers likely to line-up with Josh Gordon and Morgan Ferrier in attack.
The replay, which is set to take place at the Stadium of Light on Tuesday, 11th December, will see the Saddlers and Black Cats attempt to secure a spot in the much-coveted Third Round, with Bolton Wanderers already selected to be their opponents.
