The half-time substitute was played in by Fabio Rochemback, before rounding Brian Jensen and firing home.

Andy Gray's goal right on half-time had given Burnley the lead against their Premiership opponents.

His tap-in from under the crossbar following a neat corner routine was just reward for the Clarets after an impressive first half.

Much of the first half hasbeen spent in Middlesbrough's defensive third of the pitch, with Wade Elliott looking good on the right.

Robbie Blake was missing from the 17 with a thigh strain, while Besart Berisha and Stephen Jordan began the game on the bench.

Gabor Kiraly did make his Turf Moor debut however, with Ade Akinbiyi and Kyle Lafferty starting in attack.

It was the visitors who made the first real chance of the game on 12 minutes, with Fabio Rochemback playing in Jeremie Aliadiere, only for his low cross to go beyond a sliding Yakubu.

The Clarets suffered an early setback, with Kyle Lafferty replaced by Andy Gray after what looked like a recurrence of the knee injury picked up at Wrexham.

Joey Gudjonsson came close on a number of occasions, aiming to repeat his goalscoring exploits at the Racecourse Ground.

At the other end, Kiraly has had to be on his guard to deny the visitors, but it was Gray who gave Burnley the lead on the half-time whistle.

Elliott's corner was met by Steven Caldwell, and after he had laid the ball back to Gudjonsson, his cross was met by Duff's whose header was tapped in by Gray.
