Defender Tom Williams has announced his retirement from professional football after a career that spanned 10 years with the Club. 

After sustaining a hamstring injury in the VFL on Sunday, Williams informed the Club and his teammates of his decision to retire, effective immediately. 

The athletic defender played 85 games with the Western Bulldogs after being recruited from Morningside, Queensland in the 2004 AFL Draft.

The 27-year-old said he was thankful for the opportunity to represent the Club and that he will look back fondly at his time as a Western Bulldogs player. 

"I feel very fortunate to have spent my time in the AFL at the Western Bulldogs and with so many great people and memories."

"I am proud of my career, and although it was met with some frustrating periods with injury, I can take away countless positives."

"I thank the Club, my teammates and our supporters for their patience and support over the years and I look forward to seeing the exciting future of the Western Bulldogs unfold."

General Manager of Football, Graham Lowe paid tribute to Williams' career and in particular his contribution and resilience over an extended period of time.

"Tom is an extremely popular teammate and a much respected and admired Western Bulldogs person," Lowe said. 

"The attitude shown to his football has been exemplary, particularly through periods of injury rehabilitation - and his leadership to our developing team has been invaluable."

"As a Club, we wish Tom the very best for his onward journey and thank him for the positive contribution he has made throughout his time here."

Williams won a Rising Star nomination in 2007, and played his best season in 2010 where he featured in 23 games, including three finals.
