If Australian golfer Nick Cullen ever felt he was cruising toward a European Tour card, he won't any longer.
The reigning Australian Masters champion was sitting pretty in a tie for fifth at the halfway mark at the qualifying school final stage in Spain.
But a horror six-over-par 78 on Tuesday dropped him into a tie for 24th with two rounds remaining to fight for the 25 cards on offer for tour membership next season.
Cullen carded eight bogeys against a solitary birdie in the fourth round at PGA Catalunya Resort.
He fell into a tie at six-under 278 with countrymen Dimi Papadolos (76) and Jason Scrivener (71).
