Melbourne Storm star Cameron Smith has been issued with a warning notice for an elbowing incident with Leeds hooker Matt Parcell in the World Club Challenge on Friday.

The NRL handed down the decision after the match review committee was concerned Smith's actions could have escalated into further serious foul play, despite referee Gerard Sutton taking no action.
Smith was reacting to a tackle where Parcell lifted Smith off his feet and drove him into the turf.
A concerning act letter is often sent to players for actions which aren't considered enough to warrant suspension.
An NRL spokesman confirmed a letter was sent to the Melbourne Storm on Monday.
Ironically, if Smith was suspended he would be unable to play in his testimonial match alongside representative teammate Johnathan Thurston when the Storm play the Cowboys at Suncorp Stadium on Friday.
Smith has played 362 games for the Storm but did miss the 2008 NRL Grand Final against Manly due to suspension.
