The Western Bulldogs have re-signed midfield star Ryan Griffen for the next two seasons, ending the hopes of rival AFL clubs seeking to lure him.

The pacy 23-year-old South Australian, who has become an integral part of the Bulldogs' midfield, is believed to have been a target of several clubs, including Essendon and Adelaide.

But he said he had always planned to stay put.

"Obviously there was a bit of speculation surrounding my future, but I always intended to re-sign with the Western Bulldogs," Griffen told the club's website.

"Since moving from South Australia I have thoroughly enjoyed my time here and I could not be happier to stay at the club.

"I honestly believe the club has a very bright future and I am very excited to continue to play my part in a period of sustained success.

"We have a great group here and I am looking forward to the future."

While Griffen's commitment is an emotional boost for the Dogs ahead of the finals, they still seem set to lose another star, classy running defender Jarrod Harbrow.

The 22-year-old has been strongly linked with Gold Coast, but no announcement can be made by the expansion club until the Bulldogs' finals campaign is over.

But Bulldogs football manager James Fantasia said the club had great faith in its stock of young players, with Griffen's decision more evidence of the Dogs' bright future.

"We have seen significant development this year in our young players like Jarrad Grant, Liam Jones, Liam Picken, Jordan Roughead, Callan Ward and Easton Wood to name just a few," Fantasia said.

"These players, along with a number of others, will ensure the club remains a threat for many years to come."

Griffen is in doubt for Saturday night's qualifying final against Collingwood at the MCG, with coach Rodney Eade having said the club will make a late call on whether he has overcome a knee injury.
