NSW and Manly back-rower Anthony Watmough is out of the final State of Origin clash on July 9 after he failed to have his grade-two dangerous throw charge reduced at the NRL judiciary on Thursday.
The three-man panel of Don McKinnon, Paul Whatuira and Bob Lindner upheld the grading at Rugby League Central.
Watmough will miss four matches.
He was slugged with the charge after lifting Queensland prop Nate Myles into a dangerous position just after half-time in Wednesday night's Origin clash at ANZ Stadium.
The 31-year-old faced three games on the sidelines, with an early guilty plea.
He will miss Manly's encounters with Cronulla on Saturday, the Sydney Roosters and Canterbury in rounds 16 and 17 respectively and the Wests Tigers.
It is the second time a Blues player faced the judiciary 24 hours after an Origin clash.
Josh Reynolds fought, and won, his appeal against the grading of a similar charge in game one. AAP
