Graeme McDowell and Seamus Power have both missed the cut after play resumed at the weather-affected Puerto Rico Open.

Poor light brought an early end to the second round with American Bryson DeChambeau firing a seven-under round of 65 to hold a share of the lead on 11 under with compatriots D.A. Points and Bill Lunde, who completed his second round with pars on his three outstanding holes.

McDowell's successive rounds of 71 were not enough to keep him around for the weekend, the Portrush man missing the cut by a single stroke at two under par.

Power also will not be playing any further part this weekend.

The Waterford man carded an opening round 69, and his round was temporarily held up at the 13th, before he eventually completed a round of 76 to go finish one-over par.
