Richmond have spoken to their AFL players about on-field behaviour after Dustin Martin’s two-fingered salute to Collingwood fans.

The AFL is investigating Martin’s gesture during the game last Saturday, which came amid plenty of banter between some Tigers players and Magpies fans.

“We just want to control what we can control within the white lines – it’s something we spoke to our group about (and) we didn’t like it,” said coach Damien Hardwick.
