Riccardo Calafiori
The Italian international was forced to drop out of the starting eleven for the Brighton match after sustaining an injury in the warm-up.
Calafiori was feeling tightness in a muscle and the decision was made not to risk him.
The 23-year-old was left out of the team, with Myles Lewis-Skelly coming in to take his place.
Like Timber, it is not known whether Calafiori will be fit to take on Villa.
Expected Return Date – Unknown
