Premiership: Gloucester 26-24 Northampton
Billy Twelvetrees' late penalty ended Gloucester's losing Premiership run with victory against Northampton in a thrilling finish at Kingsholm.
Saints will feel hard done by at losing their 100% record, having led in added time from Jamie Elliott's try, converted by Stephen Myler.
Both sides scored three tries apiece, with Charlie Sharples, Twelvetrees and Elliott Stooke in for the hosts.
Ben Foden and Samu Manoa also crossed for Saints, who missed out on top spot.
Myler landed two of three conversions, and also added a penalty.
There was controversy about the penalty which settled the match, coming as it did in injury time at the end of an absorbing encounter as referee Greg Garner ruled Saints were offside at the scrum when the ball was out.
It took unbeaten Saints just five minutes to race ahead at a sunny Kingsholm, a fluid move to the right was polished off by Foden, who cut back on the inside to stroll in.
Burns' penalty after Saints were penalised for entering the ruck from the side got the Cherry and Whites on the board, although the half-back was unable to repeat the feat from further out minutes later.
The hosts were throwing the ball around nicely, and Trinder should have scored when chasing down Burns' grubber in behind, but he knocked on with the line beckoning.
Sam Dickinson was sin-binned for a tackle on an airborne James Simpson-Daniel, but despite some expansive play the hosts were unable to break through despite a man advantage.
Myler's boot pulled Saints ahead from another penalty but Gloucester had the final say of the half with a beautifully worked try from left to right, engineered by Billy Twelvetrees, Burns and Cook and finished off by Sharples under pressure in the corner.
Gloucester continued their momentum after the break and built on the lead when Twelvetrees collected Jimmy Cowan's pass inside and shrugged off a trio of tackles to force his way over.
Saints responded immediately, burrowing their way in from a rolling maul through Samu Manoa and Myler was on target to again establish the lead and could have edged further ahead had Wales winger George North not been denied a certain try by Charlie Sharples after an overlap appeared on the left.
Burns kicked Gloucester back ahead from another penalty, and they punished the Saints further when James Simpson-Daniel danced through the line and offloaded to Stooke for a try that lifted the Shed.
Saints rallied, looking for the power of their pack to dominate the hosts, but it was a powerful run from their summer import North that created the platform for a magnificent score that was finished off by Elliott, and once Myler knocked the simple conversion over it look as though there was no time for Gloucester to respond.
Not so, as Saints conceded a penalty at a third scrum with two minutes over normal time and Twelvetrees stayed calm to land the kick and seal the points.
