Maroons three quarter Wil Chambers says Cameron Munster won‘t be phased by the pressure of Wednesday nights Origin decider in Brisbane.

The Melbourne fullback will make his State of Origin debut in the match, replacing the injured Johnathon Thurston at five eight.

Chambers (pictured) says after playing alongside Munster since 2014, he’s more than comfortable with the 22 yr old in the hot seat for the decider.
