Coach Damien Hardwick says Richmond have noticed opposition runners impeding play and he expects an AFL crackdown.

Greater Western Sydney runner Nick Maxwell could be in trouble for where he positions himself at kickouts and Hardwick says he is unfussed if the league bans them.

“We’ve noticed it as well – there were two bits of vision … where they were in the way and we couldn’t believe free kicks weren’t awarded,” Hardwick said.
