It turned out to be an expensive and embarrassing happy snap. A senior Western Bulldogs player was caught out by drug testers for not being where he told them he would be when they found pictures of him on holidays.

The senior Bulldogs player had not updated the details of his whereabouts on the phone app for ASADA drug testers during the Christmas holidays.

He was then caught out when he posted photos on his Instagram account showing himself on holidays - and not in the location he said he would be.

The club was fined $5000, half of which was suspended, for the administrative sloppiness.

It was their second fine this summer for whereabouts errors after they were fined $3000 in December for not immediately informing the AFL of a change to a player's travel plans.
