knock-on

But after Sam Prendergast stretched Ireland's lead with a drop-goal and Tommy O'Brien had a try ruled out for a knock-on, Caelan Doris' 70th-minute try ensured a comfortable Irish victory.

Prendergast, restored at fly-half ahead of Jack Crowley, was the chief architect of the second, his quickly-taken kick to the corner forcing a knock-on from the retreating Max Jorgensen as the full-back tried to prevent a 50:22.

Then, after a wonderful piece of Prendergast playmaking, O'Brien's celebrations were cut short when his try was ruled out for a knock-on from James Lowe.

Prendergast looked to have set up a decisive match-winning try for O'Brien with a delightful crossfield kick but it was ruled out for a knock-on by James Lowe.

The knock-on effects of the lengthy government shutdown was also weighing on stocks Thursday.
