Steve Bruce says John Terry is a doubt for the trip to Nottingham Forest.
The manager revealed: "Unfortunately John rolled an ankle in training on Wednesday.
"We'll see how he is, but he's a doubt for the Forest fixture."
The manager also says he will make an assessment on Mile Jedinak's fitness later today.
In better news, Scott Hogan is available again having picked up a small ankle issue in the match against Bristol City.
Otherwise, Bruce says it's the biggest squad he's had to pick from for some time.
