The Western Bulldogs have been dealt a blow ahead of their clash against Fremantle, with Aaron Naughton ruled out of the Friday night fixture. Naughton will be assessed ahead of the club’s Round 22 game against North Melbourne. His teammates will board a lunchtime flight to Perth on Wednesday, hoping to upset ladder leaders on their home patch and spark their hopes of moving into the top six to avoid a finals wildcard clash. After North Melbourne next Thursday, Luke Beveridge’s men will host Carlton before facing Melbourne on the last Saturday of the home and away season. Naughton has played 185 games for the Dogs, leading the club’s goals tally in three of the last four seasons.
