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. It’s a bitter blow for the Dogs against the ladder leaders, with Naughton leading the forward line in the absence of injured young gun Sam Darcy, kicking 42 goals for the season. 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.
