Team GB's rowing line-up for London 2012 is now complete after Constantine Louloudis was named in the men's eight category.
Louloudis, 20, has overcome a back injury to earn his place in the squad.
"I'm delighted to have been selected after such a long period of doubt," said Louloudis.
"I can't wait to race at the Olympic Games this summer in London."
Louloudis claimed gold in the men's pair with George Nash at the 2011 Under-23 World Championships in Amsterdam last year, and was the youngest member of the victorious Oxford crew at the 2011 Boat Race last March, at the age of 19.
Team GB rowing team leader David Tanner said: "I'm very pleased that this completes the names for all 52 qualified slots.
"It is good news that Constantine Louloudis is now fully recovered from his injury and as an exciting, young prospect I'm sure he can really add something to our men's eight."
The British Olympic Association also confirmed that Marcus Bateman and Cameron Nichol have been named as spares for the openweight men's category, while Adam Freeman-Pask has been named as reserve in the lightweight category.
