Huddersfield Town slipped to a 1-0 defeat at Scunthorpe United as Paddy Madden's second-half goal ended Town's 100% pre-season record.
Madden struck in the 58th minute after the excellent Jennison Myrie-Williams had escaped down the right as Mark Robins' side suffered from a lack of creativity against their League One hosts.
Town began brightly enough, with Joe Lolley operating in a No.10 role behind the two frontmen and, judging by his early probing, it was clear the youngster felt completely at home there.
He sped past his marker as early as the sixth minute and floated a cross towards the back post, but saw his centre instead cannon back off the crossbar.
As well as Lolley's threat in central areas, the pace of Nahki Wells had central defenders Miguel Llera and Niall Canavan on edge from an early stage.
One dart in behind from Wells was enough to set the alarm bells ringing but a linesman's flag over on the far side halted the striker in his tracks as he fired wide.
Llera - on trial at the Iron after leaving Sheffield Wednesday - tried his luck at the other end, but saw his swinging free-kick dip just over the crossbar.
Tommy Smith started as Town's wing-back on the right flank just ahead of Lee Peltier and almost supplied the perfect cross for Wells in the middle, but the striker's hooked volley sailed over.
It was the hosts, however, who forced the first save of the contest as recent addition Myrie-Williams cut onto his favoured left-foot from his right-wing station and unleashed a vicious low strike which Alex Smithies did well to turn round the post just before the interval.
It was merely a sign of things to come.
If either of the teams were expected to return to the field with a renewed vigour, it was Town.
But Scunthorpe had other ideas, with Lyle Taylor twice going close within the first 10 minutes of the second period.
First, right-back Eddie Nolan cut inside Paul Dixon before angling in a cross which Town stopper Murray Wallace did well to clear from in front of Taylor before the striker broke the offside trap in the left-hand channel, only to see his shot flash across the face of Alex Smithies' goalmouth.
Town's start to the second-half was sluggish to say the least and they were made to pay when Myrie-Williams skipped down the right and provided a measured cross which found the onrushing Madden at the back post and the striker steered home.
Robins' side lacked imagination in their attempts to breach a stubborn Iron rearguard and the Terriers chief duly threw on Oliver Norwood and Adam Hammill in desperate search of a breakthrough.
The closest they came was when Sean Scannell's driving run down the right was followed by a fierce cross which had to be turned behind with Wells in close attention.
In fact it was Russ Wilcox's men who went closest to finding the second goal of the game as substitute Hakeeb Adelakun capitalised on a Wallace error to run at the Town defence, but could only arrow his strike over the crossbar.
With a number of substitutes entering the field, the game fizzled out as Town suffered their first loss of the close season.
