Bradford Bulls 12 Leeds Rhinos 4
The Bulls cast aside their financial woes to condemn reigning Super League champions Leeds to a third consecutive defeat on a night of high emotion at Odsal.
A bumper crowd of 20,821 turned out in Bradford's hour of need and, although of greater significance will be tomorrow's announcement on the club's future, they lapped up a memorable Good Friday victory over their arch rivals.
Not even the late dismissal of prop Bryn Hargreaves for a spear tackle on England captain Jamie Peacock could take the shine off a tremendous performance by the Bulls, who trailed for most of the match, but struck with two tries in the last 15 minutes.
The only score of the first half came after 14 minutes when Leeds centre Zak Hardaker touched down for the fifth consecutive game, taking Brent Webb's pass and stretching for the line.
Whitehead went close eight minutes into the second half when he was held up on his back over the line and substitute prop Phil Joseph was brought back for a forward pass.
The frustrations boiled over into a couple of minor skirmishes, while Bradford's French forward Olivier Elima was sin-binned on the hour by referee Ben Thaler for dissent.
Down to 12 men, the Bulls produced their best spell of the match as the bumper crowd got behind them.
Winger Shaun Ainscough, on his first appearance of the season, broke clear only to fail to use his support, but Bradford maintained the pressure and Langley touched down after Heath L'Estrange's bouncing kick caused havoc in the Leeds defence.
With the scores tied, Jarrod Sammut maintained his composure to land the angled conversion and edge his side into the lead.
Leeds simply could not get a foothold in the game and it was no surprise when the Bulls extended their lead after 73 minutes when Jeffries re-gathered his own kick to grab a second try.
Sammut's second goal gave the home side an eight-point lead.
The game ended on a sour note when Hargreaves was sent off for a dangerous tackle on Peacock, but the Bulls supporters were already in celebration mood by then.
