'What A Career': Peter Siddle Announces Retirement From International Cricket

Australian cricketer Peter Siddle has called time on a glittering international career.

Siddle was called into the extended side for the Boxing Day Test against New Zealand but was not named in the XI.

During the morning warm-up on the fourth day, Siddle told his teammates he was retiring from international cricket.

Cricket Australia confirmed the news a short time later.

"Aussie champion Peter Siddle has just informed his teammates of his retirement from international cricket," it said in a tweet.

"What a career."

That career included 67 Test matches with 221 wickets and 20 one-day internationals with 31 wickets.

Speaking to Fox Sports, Siddle said it's "always hard" to know when the right time is to make the decision to retire.

"It was sort of the Ashes (played earlier this year in England), the Ashes was the main goal, to try and get on the touring party, be a part of that series," he said.

"Once I'd sort of ticked that off, I'd been chatting with Painey (captain Tim Paine) and JL (coach Justin Langer) throughout that series.

"I thought I could have done it there, but the chance to get one last crack in Australia, to do it at home would have been nice, but I can be content."

Siddle was instrumental in Australia retaining the Ashes in the series this year and had previously won the urn in 5-0 clean sweep in 2014.

Siddle is currently playing for the Adelaide Strikers in the Big Bash League.
