Ryan Harris has insisted that he is focused on appearing for Australia in the Ashes series against England in 2015.

The pace bowler is expected to spend six months on the sidelines after undergoing surgery on his knee, but he believes that the injury setback will not bring his career to a premature end.

"It's nowhere near my career [being] over," Harris told reporters. "I did this to play longer, more than anything. I still aim to play five Tests in England if I make it and two Tests against Pakistan in October.

"I'm still able to play back-to-back stuff. Those sorts of decisions are out of my hands.

"They're up to the medical staff or the coaching staff but I've shown I can do it. My knee is bit more damaged than the last time they operated a few years ago but it's still a good knee and with what I put up with over the last few weeks, I can probably put up with just about anything now."

The 34-year-old has taken 103 wickets in 24 Test matches for Australia.
