Queensland veteran Sam Thaiday was on Wednesday night slapped with a grade-two dangerous throw charge for a spear tackle on NSW captain Paul Gallen at Suncorp Stadium on Wednesday night.

In an ugly incident in the 13th minute of Origin II, Gallen was up-ended in a tackle in which Maroons lock Corey Parker was also present but it was Thaiday who was principally responsible for leaving the Blues skipper tipped on his head.

Thaiday's charging leaves him in danger of being being rubbed out of the final match of the State of Origin series. He has no carryover points but will accrue 243 points - a two-match ban - if he takes the early guilty plea. If he does not and fights the charge and loses at the judiciary, Thaiday will pick up 325 demerit points and miss three matches.
