Following a horrid run with injuries, which included three knee injuries that derailed his 2013, 14′ and 15′ seasons, the 23-year-old played 13 games last season, including the Dogs’ grand final win.
He has now played a total of 51 games and is an important part of the Bulldogs’ forward line.
“Clay’s one of those heart and soul players, crucial to the success of any football club, Bulldogs list manager Jason McCartney told the club’s website.
“The way he fought back from injury and performed at a high level is a tribute to his character and tireless dedication to our football club.”
Meanwhile, the Dogs have also re-signed youngster Patrick Lipinski for a further season, after adding a year onto his existing two-year draftee contract.
“Patty has shown some really encouraging signs at VFL level, and we think he has significant upside as a medium-sized forward,” McCartney said.
“He’s a smart user of the football, who’s versatile enough to be used on a wing or through the midfield.”
Lipinski, who is yet to make his senior debut, was selected with pick No.28 in last year’s National Draft.
