Challenge Tour — Moyola Park's suffered a reoccurrence of a tendonitis injury and was forced to withdraw after just eight holes of the weather-delayed Cordon Golf Open in France.
The former East of Ireland and Irish Close champion, 25, hurt his wrist at the Second Stage of the Q-School at the end of 2015 and has suffered inflammation problems already this season.
Two-under par when he was forced to pull out at Golf Blue Green de Pléneuf Val Andre, he reported: "It's reoccurrence of my tendonitis injury from May/June unfortunately.
"I don't know how long I'll be out for as it was so inflamed today when getting treatment, but I'll know tomorrow. Hopefully, it's only a week or two. It's very frustrating. I was playing lovely."
Chile's Nico Geyger starred on the first day as a thunderstorm and heavy rain prevented round one from being completed.
The Chilean started his round with four straight birdies before two more either side of the turn took him to six under par, one ahead of the clubhouse leader Thomas Perrot, before play was suspended for the day, initially for lightning and then due to a waterlogged course.
Out in the perfect morning conditions, Perrot’s five under par round of 65 featured an eagle and three birdies, while his compatriot Pierre-Yves Rolland – playing at his home course as a qualifier – shot an impressive 69.
Of the other morning starters to complete their rounds, Jules Coupade, Oliv Rozner and Marcel Schneider were the most notable, all signing for rounds of 66 to sit two off Geyger’s overnight lead.
Michael Hoey is the best of the Irish, tied for 17th on two-under through 10 holes with Mount Wolseley's Gavin Moynihan and Mount Juliet's Kevin Phelan in the clubhouse on one-under after one-under 69s.
Moynihan did very well to break par, storming home in four-under 31 after starting with a bogey at the first and a double bogey six at the fourth.
It was also a good day for Phelan, who has struggled this season and made just one cut from his last nine starts.
Rory McNamara carded a three over 73 to share 118th with Ardglass' Cormac Sharvin, who had nine holes of his first round to complete while Golf Clement Ader's Tommy O'Driscoll is tied 125th after a 74 that featured five birdies, six bogeys and a triple.
