Gary Hurley and Darren Clarke have work to do to make the cut in the D+D REAL Czech Masters in Prague.
The West Waterford man recovered from an early triple bogey seven at the fourth but signed for a one-over 73 that leaves him tied for 79th at Albatross Golf Resort with Clarke 101st after a late double saw him sign for a 74.
England's Callum Shinkwin showed no signs of rust after his five-week break as he fired a six under par 66 to leave by one stroke from South African Dylan Frittelli, Swede Pontus Widegren and Englishman James Heath.
Felipe Aguilar, Jaco Ahlers, Chris Hanson, Peter Karmis, Craig Lee, Oscar Lengden, James Morrison and last week's Made in Denmark winner Julian Suri are tied for fifth ater 68s.
Defending champion Paul Peterson was then alongside 2014 winner Jamie Donaldson in a group of 14 players at three under.
