The Warriors prop Charlie Gubb will miss the rest of the NRL regular season after being hit with a seven-week suspension for his his shoulder charge on Manly's Darcy Lussick.
Gubb unsuccessfully challenging the grading of the charge at the NRL judiciary last night.
He was cited for the shot at the 13-minute mark of the Warriors' loss to Manly last weekend in Perth.
Gubb failed in his bid to have the grade-two count downgraded and was found guilty by the judiciary.
Gubb and McFadden were left devastated.
"I'm in shock," said McFadden immediately after the decision was reached.
"We believed there was a strong case for having the charge downgraded to grade one but the judiciary didn't see it that way. It's devastating for Charlie and for the team that he won't be able to play again in the regular season.
"He's an important player in our group with the energy and intensity he brings. We'll miss what he provides but we're just going to have to adapt now to operating without him for the next seven games."
