McIlroy misses cut at Irish Open
Ilonen added a 2-under 68 to his opening-round course record of 64 to move to 10 under on the Fota Island Resort course.
The 34-year-old Finn birdied his opening hole but then stalled with eight straight pars ahead of an inward half that included four birdies.
"I wanted to at least get to 10-under par, and I did that," Ilonen said.
McIlroy's double bogey came after his tee shot clipped a tree and ricocheted out of bounds and over the fence into the adjoining Fota Island Wildlife Park.
"I'll be back next year and try and do better," McIlroy said.
