Wood has been absent from Test cricket for over a year.
England's pace spearhead Mark Wood says he is "quietly confident" about his fitness for the first Test of cricket's greatest rivalry in Australia.
The cricketer has been sidelined following a Champions Trophy loss against Afghanistan in February and underwent surgery on a left knee injury this spring.
The Champions Trophy and India series that preceded it was the 35-year-old's return after an elbow problem that had kept him out for many months.
"The summer was disappointing," Wood stated. "I was unable to participate in any cricket and my knee, at times, when it seemed I was nearly fit, it was not just quite there."
"I got knocked back a couple of times, but during the training camp progress has been positive. I've had the speed gun out and my speed is increasing."
The first match of the Ashes begins November 21st at Perth, with England aiming to win their first Test series in Australia since 2010-2011.
"Hopefully, I'm in form, bowling well in the practice games and in net sessions, and can make my case for the first Test," Wood continued, whose last Test outing was against Sri Lanka over a year back.
"The rehab hasn't just been a straight curve, it's been a bit up and down, but now I'm in a better place where i'm hoping to kick on toward the match."
"I never want to give an answer where I say, 'Yes, I'm pumped, I'm ready'. I'm in a confident place currently and more optimistic, so I'm quietly confident."
At the same time, worries for Australia regarding the health of players has resulted in player Cameron Green being replaced by Marnus Labuschagne for the ODI series with India, beginning this weekend.
The Aussies also have doubts about the fitness of captain Pat Cummins, who has not played since mid-year because of lumbar bone stress in his back.
"Cameron Green has been ruled out for the India series after suffering mild side discomfort at training this week," the cricket board stated.
"He will undergo a brief rehab stint and is tracking to return to play in round three of the Sheffield Shield to continue his preparation for the series."
Round three of Australia's domestic Sheffield Shield competition is scheduled to start October 28th.
