JASON Gillespie has called his three-year contract with Glamorgan into doubt by announcing his retirement from first-class cricket in Australia to join the rebel Indian Cricket League.

The 32-year-old paceman will end his career with South Australia at the end of the current Pura Cup clash against Queensland at the Adelaide Oval.

Gillespie insisted he was not "up to speed" with the England and Wales Cricket Board's increasingly frosty stance on unsanctioned competitions - but with the world game now lining up firmly with the official Indian Premier League there could be trouble ahead.

Earlier this week the ECB issued a statement which hinted at difficulties ahead for players who wished to play both county cricket and ICL Twenty20.

Yorkshire, meanwhile, insisted their overseas signing, Pakistan seamer Rana Naved-ul-Hasan, would have to make a choice between a future at Headingley or the rebel league.

But Gillespie, nicknamed Dizzy, who played for the White Rose county last year, insists he intends to honour both agreements: "I'm not up to speed with all those things. I've got a contract and I certainly fully expect to fulfil that contract with Glamorgan," he said.

"But I'm very excited (about the ICL) - it certainly is a change.

"But it's something I'm very much looking forward to. It's just an opportunity to do something a little bit different and it's exciting.

"The opportunity came up and I had to weigh things up. I wasn't sure what I was going to do - whether I was going to play on another season with South Australia.

"The body is feeling good so we'll see how we go. Obviously I can't do the things I could do six or seven years ago, but I still feel I'm contributing."

In a career of 175 first-class matches since 1994, Gillespie has taken 588 wickets at an average of 26.43 and is sixth on the list of Australia's Test wicket takers.

"Cricket has been very good to me. I've travelled the world, I've met some fantastic people and I've spent my time doing the thing I love the most, which is playing cricket.

"But it has always been important to me to end my career on my own terms while I'm still contributing. I do not want to get tapped on the shoulder and shown the door," he said.
