Christian Saydee grabbed his first Town goal as Shrewsbury fell to a stoppage-time defeat at Port Vale.
In what was Town’s first defeat on the road this season, the hosts took a ninth-minute lead through Ellis Harrison.
Saydee pulled the scores level after he combined excellently with Rekeil Pyke.
But in a match of few clear-cut chances, Vale won it in added time when Harrison nodded in his second goal of the game following a corner.
Boss Steve Cotterill opted for a 3-5-2 formation at Vale Park, with Saydee making his first start up front alongside Pyke.
Carl Winchester made his full debut at right wing-back with George Nurse on the left and Luke Leahy, Taylor Moore and Tom Bayliss the midfield three.
On the bench, Elliott Bennett was included in the matchday squad for the first time this season after recovering from an ankle injury.
Port Vale lined up in a 3-4-1-2 system with Dan Butterworth in the number 10 role and Ellis Harrison partnering former Manchester United player James Wilson.
It was Vale who flew out the blocks, with Darrell Clarke's side taking the lead in the ninth minute.
Following a swift counter-attack, the ball was worked to Harrison in the box, who calmly slid the ball past Marko Marosi and in.
Shrewsbury didn’t stay behind for long, with Saydee pulling them level with a wonderfully worked goal.
First, the forward produced an outrageous back heel to find his strike partner Pyke in the box.
Pyke then produced a clever return pass with Saydee using his strength to hold off a defender before brilliantly slotting the ball into the bottom corner.
Following what had been a frantic start, the game then quietened down for the rest of the half, with neither side creating a chance of note.
Harrison had the first opportunity after the restart as he tried his luck from 25 yards out, but Tom Flanagan made a smart block to remove the danger.
Shrewsbury had a chance to take the lead with 20 minutes remaining, with Flanagan smartly playing a through ball to Ryan Bowman.
The substitute weaved around some Vale defenders and had a shot that looked destined for the bottom corner. But his effort took a deflection and sailed narrowly wide.
With five minutes to go, Leahy let fly with a swerving strike from 20 yards out that went just inches over.
But in the 90th minute the hosts went on to win it. Following a corner, the ball got whipped into the box with Harrison rising the highest to head in.
