Clipstone found out just how tough the NCEL Premier Division is after they were beaten 2-0 at home to Barton Town Old Boys.
Clipstone had started the day at the top of the table having gained seven points from their opening three league games.
The away side had the first real when they hit the crossbar.
Clipstone manager James Colliver was forced to shuffle his pack when Michael Trench was unable to carry on after pulling up with a muscle strain on 15 minutes.
Brad Jones superb run was ended by a smark tackle after he had beaten four defenders.
Barton keeper Scott Drury was on hand to deny Clipstone once again on 27 minutes as he denied Jahmal Smith.
Moments later Jordan Hodder ran onto a free ball 22 yards out and unleashed a tremendous shot across the face of goal, missing the far post by an inch or so.
The second half started in controversial fashion when the visitors were awarded a penalty after a collision in a 50/50 challenge between keeper Steve Hernandez and a Barton attacker.
The Cobras were incensed by this decision and referee cautioned Hernandez and Damian Magee, the latter for remonstrating with the official.
Brad Rickets stepped up to dispatch the ball beyond the keeper to open the scoring.
It was not long before Barton doubled their lead in bizarre circumstances when Liam Nelthorpe mis-judged a throw-in and headed past his own goalkeeper.
