Sunderland midfielder Elliot Embleton could return from a serious ankle injury before the end of the season.
Embleton sustained the damage in a high challenge on Ryan Woods which also earned him a red card in the 1-1 draw.
"I think he was having his operation today. I think footballers when they get bad injuries there is emotion for them," manager Tony Mowbray said.
When asked if Embleton could feature again this season, Mowbray said: "The hope is yes. Every player reacts differently to injuries but I would hope we see him again this season.
