The intricacies of the video referee have halted Canterbury's bid for the NRL top four as Gold Coast moved into finals reckoning with a 26-16 upset at ANZ Stadium.
A Kevin Gordon hat-trick helped the Titans secure just their second win from the past six games to leap ahead of Canberra into eighth spot on the ladder, the Bulldogs now trailing fourth-placed Melbourne by five points with four rounds remaining.
The home side was left to rue a controversial video referee ruling when Josh Reynolds was denied a try in the 52nd minute which would have given the Bulldogs their first lead.
The on-field officials ruled no-try as they sent it upstairs, and despite replays indicating the ball hitting Jamie Dowling's head and not Josh Jackson's hand, the original decision was upheld due to insufficient evidence.
The impact of the call was exacerbated when David Mead crossed off a delicate inside ball from Luke O'Dwyer four minutes later to give the Titans an 18-10 lead.
