Claims by NSW captain Paul Gallen that Billy Slater won't be targeted in State of Origin Game 2 appear to have been taken with a grain of salt by Queensland skipper Cameron Smith.

Smith could not rule out the possibility of the Blues seeking some serious payback for Slater at the MCG tonight.

Blues captain Gallen reckoned injuring Slater was the last thing on their minds as they looked to square the series.

The Maroons face the Blues at 10 tonight.
