Burnley boss Sean Dyche has just 17 players to choose from ahead of the Europa League third qualifying round against Istanbul Basaksehir.
The Clarets will play the first leg in Turkey on Thursday night.
"We're a little bit limited and we'll have a few decisions to make," Dyche told a press conference.
"Chris (Wood) has an infection from a bite that has caused a reaction. Steven (Defour) is behind Robbie (Brady) at the moment, so we're down to 17 players.
"But Joe (Hart) and Ben (Gibson) have travelled for a reason - to be included if needed."
