Gold Coast fullback Keano Kini conjured up the attacking play of the season to sink Brisbane 28-23 and leave the NRL premiers' title defence in ruins.
A 73rd-minute Adam Reynolds field goal appeared to have taken the Broncos to victory at Suncorp Stadium on Saturday, before Kini, from 55m out, chipped ahead and snatched the ball from Reece Walsh's grasp to race away in the 77th minute.
Kini then saved a last-gasp try attempt by the Broncos when he knocked the ball dead to secure one of the club's great wins and break a five-game losing streak.
"Special players do special things," Titans coach Josh Hannay said.
"We love that young lad because he might drop a ball early but it doesn't stop him. He keeps going after the contest, and he went after it right to the very end and came up with a special play.
