The Western Bulldogs have locked away key defender, Marcus Adams, for a further three years.

Adams, who missed out the Bulldogs' first premiership since 1954 due to a foot injury, which cut short his first AFL season after an extremely impressive 11 games, will now be a Dog until 2020.

The 23-year-old has missed just the one game so far this season, averaging 15.5 disposals and six marks.

“It’s great to be able to extend my contract at the Bulldogs, and I’m looking forward to improving with every season,” Adams said.

“Last year was a great experience for me to play the games I did.  It was frustrating to deal with the injuries I had, but I took a lot out of the season.

“I want to establish myself in this team, and do whatever I can to help the team achieve success.”

List manager, Jason McCartney, said the club is thrilled to re-sign Adams, who had offers to return home to Western Australia.

“We believe Marcus has a big future at the Bulldogs, and we’re thrilled to see him extend his contract,” McCartney said.

“We see him as a key pillar of our defensive unit, with his athleticism and intercept marking his standout traits.  He is progressing very well.

“Through necessity he has gone forward at times this year and has been a threat, which has added another string to his bow."
