Bradford Bulls 16 Leigh Centurions 20.

Ed Chamberlain finally ended Leigh’s Odsal jinx with Adrian Lam side’s on the cusp of heading out of the Betfred Challenge Cup.

Chamberlain scored a dramatic 78th minute try to book a sixth-round trip to Super League Hull KR later this month.

Trailing 16-14, the centre’s touchdown from Keanan Brand’s brilliant offload spared the visitors’ blushes and gave Leigh their first win on Bulls territory since 1994.

But it was too close for comfort for Centurions who trailed 8-0 in the first half and 16-8 in the second with Caleb Aekins yellow carded by referee Marcus Griffiths.

But Nene Macdonald and then Chamberlain came up with tries in the last 13 minutes, both goaled by Ben Reynolds to snatch victory from the jaws of defeat.

Leigh’s first win in six attempts at Odsal was also their first over Bradford in the Challenge Cup since the Wembley winning year of 1971.

Leigh enjoyed plenty of early possession but when they failed to clear the ruck, Bradford took a 16th minute lead through Dec Patton’s penalty.

Adam Sidlow almost delivered the perfect response but the ex-Bulls forward was held up over the try line. Joe Mellor’s then generated too much power on a stabbed kick behind the whitewash and Bradford survived.

Leigh’s defence was found wanting as the Odsal outfit extended its lead. Centurions’ right edge had previously been tested and just about held firm.

This time it cracked as Patton, Kieran Gill, Ryan Millar and finally Gill created and finished a picture book try. Patton kicked the extras to make it 8-0.

Leigh finally put points on the board six minutes from the break. A set re-start was the platform for Adam Sidlow to score against his old club. Reynolds kicked a routine conversion.

Reynolds, upto 10th on Leigh’s all-time points scoring chart, potted a 39th minute penalty to tie the scores at half-time.

Centurions, however, couldn’t eradicate the errors to build sustain pressure. Defensively, the visitors were always being tested.

They escaped one scare as Sam Scott scythed his way to within 10 metres of the line.

And full-back Aekins, Leigh’s hat-trick hero in the previous round, was sin binned for a professional foul on Matty Dawson-Jones.

The former Leigh winger wasn’t to be denied and George Flanagan’s looping basketball style off load was gleefully grounded in the corner by Dawson-Jones.

Patton booted a touchline conversion and added a penalty to restore Bradford’s eight-points cushion.

Leigh badly needed a response and with 13 minutes remaining Macdonald crashed over after Bulls were caught offside attacking Mellor’s angled kick. Reynolds goaled to reduce Bradford’s lead to 16-14.

With the clock ticking down Reynolds kicked to the corner, Brand collected and off loaded to Chamberlain for the decisive score.
