Brisbane’s Luke McGuane has cost himself another $500 with an unsuccessful challenge at the AFL tribunal.

McGuane was initially fined $1000 by the match review panel for rough conduct against Carlton’s Kade Simpson.

He opted to challenge at the tribunal but failed and instead was fined $1500.

The tribunal is about to hear cases against Fremantle’s Alex Silvagni (striking) followed by West Coast’s Chris Masten (biting).
