Alan Campbell squeezed into Saturday's heavyweight single scull final at the World Rowing Championships when he took third in Thursday's semi-final in Eton.
Coleraine rower Alan Campbell won this year's World Cup series
The Coleraine man led early on but appeared to struggle in the middle of the race before producing a late rally to claim the final qualifying spot.
Ondrej Synek of the Czech Republic won the semi-final in 6:45.12 ahead of Olympic champion Olaf Tufte (6:46.52).
Campbell clocked 6:47.43 to pip Cuba's Yoenis Hernandez-Arruez (6:48.54).
Campbell won the World Cup series this year and has been strongly tipped to secure a medal at Eton.
However, illness prevented him from competing well in Sunday's first round although he improved to comfortably win his repechage on Tuesday.
The Coleraine man said he was delighted to make the final although he acknowledged that he had been "in a bit of trouble" in Thursday's race.
"I let Synek and Tufte get the better of me today," said Campbell.
"But this was my first real test this week from beginning to end so I hope you'll be seeing something more from me in the final."
Meanwhile, the Irish men's heavyweight four of Cormac Folan, Sean O'Neill, Sean Casey and Alan Martin missed out on qualification for the final of their event.
They finished fifth in a tough semi-final won by Britain.
The Irish quartet will contest the B final on Saturday for places seven to 12.
