Wood has been absent from Test cricket for over a year.
England's pace spearhead Mark Wood says he is "quietly confident" of being fit for the opening match of cricket's greatest rivalry in Australia.
Wood has not played since a Champions Trophy defeat by Afghanistan last winter and had an operation for a knee issue this spring.
That tournament and India series that preceded it was the 35-year-old's return from an elbow injury which sidelined him for many months.
"It was a frustrating summer," Wood stated. "I was unable to participate in any matches and my knee, at times, when you think that you're just about ready, it was not just quite there."
"I got knocked back a couple of times, but in the tent [training camp] progress has been positive. We've used the radar gun and the pace is getting up there."
The first match of the Ashes begins November 21st at Perth, with England aiming to win their first Test series in Australia in over a decade.
"Hopefully, I'm in form, delivering effectively in the practice games and in net sessions, and can put my hand up for that game [Ashes opener]," added Wood, who last played a Test versus Sri Lanka 14 months ago.
"The rehab hasn't just been a straight curve, it's been a bit up and down, but I'm in a good position now where i'm hoping to kick on toward the match."
"I avoid making statements where I say, 'Yes, I'm pumped, I'm ready'. I feel assured at the minute and more optimistic, so I'm quietly confident."
At the same time, Australia's concerns over the fitness of players has resulted in all-rounder Cameron Green being replaced by Marnus Labuschagne for the three-match one-day series against India, beginning this weekend.
The Aussies also have doubts about the fitness of skipper Pat Cummins, who's been absent since mid-year because of lumbar bone stress affecting his spine.
"Cameron Green has been ruled out of the [India] series having experienced mild side discomfort at training this week," Cricket Australia said.
"Green will complete a short period of rehabilitation and is expected to be back for the third round of the Sheffield Shield to continue his preparation for the series."
The third round of the Sheffield Shield tournament is scheduled to start October 28th.
