The Bulls produced an utterly unbelieveable comeback to stun league leaders Wigan at Grattan Stadium.

Seemingly dead and buried when they went in 20-0 down at the break, Bradford launched the most unexpected of comebacks to snatch the points with almost the last play of the game.

Glenn Hall powered over the line in the last minute and Matt Orford added the conversion to seal a 22-20 win.

Following an indifferent first half, Orford had been key to the comeback, at the centre of everything good in the second half.

The scrum half had a hand in the build up to Brett Kearney's try early in the second half and then scored himself, converting both to cut the gap to eight.

He then doubled his personal try tally seven minutes from time before Hall sent the Bulls faithful into raptures.

It had all seemed so unlikely after Darrell Goulding, Harrison Hansen, Sam Tomkins and Pat Richards had touched down during a dominant first half from the Warriors.

But the Bulls showed incredible resilience to seal a win that lifts them to seventh in Super League with three wins from five.
