Shane Lowry will miss the weekend action at the Dubai Duty Free Irish Open as a second-round 72 was not enough for the Offaly man to make the cut.
The 2009 champion was two over today and seven over overall, two shots outside the projected cut mark.
Lowry improved on yesterday's disastrous 75 with a round that featured three bogeys and a single birdie but a three-putt from four feet on 10 proved costly and he could only par the last four holes as he sought to close the gap.
Englishman Aaron Rai is now the outright leader at Galgorm in Ballymena despite only shooting a level-par 70.
South Africa's Dean Burmester's 71 saw him slip back to second, where he is joined on four under by England's Robert Rock and Swede Joakim Lagregren. Lagergren's 66 was the lowest round of the day.
A 90-minute morning frost delay meant that 27 players were unable to finish their second rounds on Friday, with Rai's fellow Englishmen Toby Tree and Jordan Smith and Australian Maverick Antcliff best placed of those with holes remaining to snatch the halfway lead. Antcliff was three under for both his round and the week with eight holes left to play.
Tree and Smith were three under for the week through 14 and 15 holes respectively, with another Englishman in Robert Rock in the clubhouse on four under alongside South Africa’s Dean Burmester and Sweden’s Joakim Lagergren.
There should be five home players involved in the final two rounds.
Colm Moriarty's 69 took him to four over while amateur Mark Power birdied three of his last five holes for a 71 that propelled him into the top 60 and ties.
James Sugrue (level par through 16 holes), Damien McGrane (+2 thru 13) and Jonathan Caldwell (+2 thru 10) must all finish their rounds in the morning as poor light ended play, after today's delayed start due to frost on the course.
2007 winner Padraig Harrington was six over after an unlucky bogey on his final hole while Paul Dunne (+9), Gavin Moynihan (+11), amateur Tom McKibbin (+11) and Cormac Sharvin (+17) all also missed the cut.
