“I tried my best to make the last game but I couldn’t bowl at the intensity and speeds required to play for England,” Wood told the BBC.
“I couldn’t get my hip going. Hopefully if required I can try and get it right for this game -- I don’t know if I’ll be able to.
“The team did really well last game -- if the captain desperately needs me and I’m fit enough then I’ll put my name in the hat like everyone else.”
Wood’s pace has added bite to England’s attack in Australia with the 32-year-old claiming nine wickets in the group stage of the tournament.
The fast bowler missed the Indian Premier League this year after sustaining an elbow injury during England’s test series in the West Indies and the team will hope he recovers before their Test series in Pakistan which starts on 1 December.
