Melbourne will speak to two of its players after they attended Mad Monday celebrations dressed up as Rolf Harris and a young girl.

A photo of the pair, posted on defender Dean Terlich's Instagram account features Terlich and teammate Alex Georgiou dressed up in costumes that appear to be the disgraced musician and a girl. Terlich is wearing a fake goatee, high grey wig, short tie, colourful shirt, blazer and rectangular glasses, all of which are trademarks of Harris.

Georgiou is wearing a dress and wig.

The club indicated that it will speak to the players about their costumes sometime between when they return to headquarters on Wednesday.
