The Bulldogs are confident star playmaker Tom Liberatore will overcome concussion for Saturday night's clash with Richmond at Etihad Stadium. Ruckman Tom Campbell – a late withdrawal from the loss to Greater Western Sydney – will need to pass a fitness test on his ankle. Veteran Matt Boyd should slot straight back into the half-back line after missing a week with a back complaint. Mitch Wallis (broken leg) and Tory Dickson (abdominal) had impressive VFL returns from injury layoffs, but both are unlikely to be considered for senior selection. Running defender Shane Biggs responded to being dropped for the second time in a month by collecting a game-high 35 possessions in Footscray's 124-point win over North Ballarat. Third-year midfielder Lukas Webb put his hand up again for a senior recall with 32 touches. - Ryan Davidson
