Brian Noble’s Wigan moved within one game of the Grand Final for a third successive year with a 30-16 win over Hull KR.
Noble has led the Warriors to the semi-finals in the play-offs in each of the past two seasons, but the Warriors have missed out on a Grand Final spot both times.
They will now have to wait and see who they play next weekend for a place at Old Trafford in a fortnight.
Chaz I’anson then reached over for a try and after much deliberation from the video referee, Dobson was able to cut the gap to 18-16.
But just as the Robins fans expected their side to take the lead, Martin Gleeson took Paul Prescott‘s pass to cross for a try, and the former St Helens and Warrington centre went over for a second try in the closing stages to seal the win for the visitors.
Wigan will face either Leeds or St Helens, depending on whether the Rhinos to face them or Catalans in Sunday’s Clubcall, televised live on BBC2 and Sky Sports News at 1.30.
