Sam Vokes’ 10th goal of the season extended the Clarets’ unbeaten run to 10 league games in the gritty 1-0 win over Nottingham Forest.
The solitary strike, 23 minutes from the end of a tight contest, was the Welshman’s goal sixth in nine games and kept the Clarets just one point behind leaders Hull City.
The Clarets also recorded their fourth clean sheet in a row for the first time since April, 2007 as their momentum builds at a crucial time of the season.
Defender James Tarkowski made his full debut for the Clarets, replacing the injured Michael Keane who picked up a head injury last time out.
And there was a fine pace to the first half by the Clarets, who controlled possession.
Andre Gray continued his tireless effort from Saturday’s victory over Rotherham, and the forward came close with two early chances.
Joey Barton’s inch-perfect free-kick found the onrushing forward six-yards out, but the league’s top scorer couldn’t steer his header on target.
Gray was then on the end of a clever Scott Arfield through ball, turning captain Matt Mills on the edge of the box only for a fine Michael Mancienne block to send the effort wide.
The resulting corner brought another Gray effort, with David Jones’ deep set-piece headed out to the former Brentford striker, where Gray’s acrobatic back-heel brought a flying save from De Vries.
Two more chances then went amiss for the Clarets, as half time approached.
Stephen Ward’s turn on the by-line teed up a low cross to Sam Vokes on the penalty spot, but another block from Mancienne denied the Welshman.
And the half’s best chance came in stoppage time, when Jones’ initial half-volley was parried wide.
The ball worked its way back to the midfielder at the edge of the box, who again forced a parry from De Vries, which fell to Gray, who smashed over.
In contrast to the first half the second was a slow burner, taking 20 minutes for the first chance to fall.
Bojan Jokic’s pull back to the edge of the 'D', but the former Derby County forward failed to keep his powerful strike from rising.
But midway through second half the Clarets finally broke the deadlock!
Following neat work by Barton and Gray, Ward’s cross from right on the by-line was cleverly dummied by George Boyd to Vokes, who slotted home effortlessly from six-yards out.
The Welshman then turned provider to Boyd with a flick-on, but the former Forest loanee pulled his 20-yard strike wide of the near post, before Gray’s strike then also found the same destination.
The remaining 15-minutes offered no chances however, with the Clarets solid at the back to seal back-to-back home wins ahead of the visit to Bolton on Saturday.
