The Western Bulldogs have informed both Fletcher Roberts and Lukas Webb they will not be required for 2020.

Roberts - who was a member of the Dogs' premiership-winning side in 2016 - exits the club after eight seasons and 51 games.

Webb played 24 games over five seasons, but didn't feature in 2019.

“We thank Fletcher and Lukas for their contributions at our football club,” Dogs' General Manager of List and Recruiting Sam Power told the club's website.

“Both were part of team success in 2016, with Fletcher an important member of our AFL premiership side and Lukas among the best performers in Footscray’s VFL triumph.

“They have been well-respected members of our playing group, and we wish them all the best for the future.”
