Wood is tackled by Furet

Ben Gollings dived over in the corner, with Burke extending the advantage with a successful conversion.

Quins kept their noses in front until Ignacio Corleto scored the French side's first try of the game on 30 minutes.

Burke and Quesada then swapped a succession of penalties before Pat Sanderson crossed over for Quins' second try 15 minutes after the break.

Burke's conversion made the score 23-19 to the English side, but Narbonne remained a huge threat.

Even when scrum-half Gregory Sudre was yellow-carded and Burke had added another penalty to open a seven-point lead, Stuart Reid's men refused to throw in the towel.

With just five minutes of normal time left, they levelled matters when Argentine hooker Mario Ledemso touched down and Quesada landed a difficult conversion.

Quins began extra time with a flourish, Daren O'Leary profiting from Will Greenwood's powerful surge to crash down under the posts.

Winters goes on a break

Burke kicked the conversion and then booted another penalty to make the score 36-26 after Australian flanker David Wilson had been stretchered off with a knee injury.

But Narbonne came back again, Reid scoring a debatable try in the dying seconds of the first half of extra time.

The Scottish No 8 bundled his way to the Quins' line but seemed to lose control of the ball as he went to earth.

Yet Welsh referee Nigel Whitehouse, who was right on the spot, deemed that Reid had grounded the ball legitimately.

Quesada then reduced the deficit to three points with his seventh successful kick at goal.

Narbonne had chances to take the game by the scruff of the neck but fell victim to Burke.

After extending the lead to six points with yet another penalty, the Quins fly-half landed a drop goal with just over a minute remaining to seal a memorable win.
