The NRL will move swiftly to close a loophole in its new judiciary code that will allow Will Chambers to escape a one-game ban as the man he left dazed and confused, Blues No.7 Mitchell Pearce, admitted he felt "sea sick" and is unlikely to back-up for the Roosters.

Melbourne exposed an ambiguity in the NRL's judiciary guidelines – introduced this year to impose fines for minor-grade offences rather than suspensions – that will free the Queensland centre to play for the Storm against the Knights on Friday night.

Chambers was hit with a grade-one careless tackle for his shot that concussed Pearce midway through the Blues' record 28-4 romp, the third time this season he has been charged. A third strike is supposed to forfeit a player's right to a fine rather than suspension.

But the Storm's legal team argued the code only made reference to a suspension being triggered after a third conviction rather than charge, allowing Chambers to escape a ban.
