“They [Zaha and Wan-Bissaka] have both been nursing injuries,” Hodgson said in a pre-match conference.
“However, they were out in training this morning, so if nothing happens in terms of reaction overnight, I’m hoping they will be fit to play but it is touch-and-go.
“Bakary [Sako]'s back. Mama [Sakho]'s the only one we have out at the moment. It's a great compliment to our Sports Science department that we only have one out at this stage in the season.”
Crystal Palace are 13th in the league standings with 33 points from 30 games.
