Darren Clarke has missed the halfway cut at the Houston Open.
The Dungannon man carded two double-bogeys in a five-over-par 77.
Clarke started with a 71 on Thursday and he moved to two under after a steady front nine in the second round.
But a poor back nine, including double-bogeys saw Clarke finish on four over and eight shots shy of the cut mark,
American Andrew Putman leads by one stroke on 12 under.
Clarke will play in his 13th Masters next week alongside Rory McIlroy and Graeme McDowell.
