Petrie admits gambling is a problem in AFL

NORTH Melbourne veteran Drew Petrie (pictured) says he wasn't aware of any problem punters at his club, but did admit gambling was the "biggest social problem in AFL football".

The 32-year-old, who is on the AFL Players' Association board, was speaking on afl.com.au's weekly podcast, AFL Exchange, following revelations former St Kilda and Hawthorn player Brent Guerra had lost $400,000 on the punt over four years while he was at the Hawks.

Petrie said he had asked himself whether there was any more he could do to ensure gambling did not become a serious problem for someone at the Kangaroos.

"I'd hate for anybody at North Melbourne to, in three or four years time, to come out and say they lost a lot of money, they lost their house and I was at the club and I was aware they gambled but did nothing about it," Petrie said.

Guerra will soon join the AFL's overhauled responsible gambling program.
