Canterbury coach Des Hasler has ducked tough questions about his side, walking out on a pre-game media conference.

While the Bulldogs sit in sixth going into Sunday's NRL clash with Wests Tigers, they are being accused of underperforming, with club great Terry Lamb questioning the coach's understanding of what he calls the "club culture."

In addition, former representative back-rower Tony Williams is rumoured to be on the outer after being dropped to reserve grade for this weekend.

He is fighting to stay on at Belmore next year.
