Fernando Forestieri is back available for selection as Wednesday travel to league leaders Newcastle on Boxing Day.
The 26-year-old has served his three-match suspension following his dismissal in the victory over Preston earlier this month, where his goal helped the Owls on their way to a 2-1 victory.
Forestieri has scored three goals in his last three games, also hitting the target against Fulham and Wolves.
Carlos Carvalhal said: “I am happy when all the players are back and available to play.
“I am happy because we have more options to decide and it’s a positive headache to us.
“A concern is when we don’t have players and that is red alert.
“Even though we have doubts on some players, we are no more than on yellow alert. But all the time we go to the pitch to fight for the three points for sure.”
