Shane Ryan, the former US swimmer who declared for Ireland last year, will attempt to become the second Irish competitor to qualify for this summer’s Rio Olympics at the Luxembourg Euro Meet this weekend.

Ryan [22], whose father hails from Portarlington, will compete in the men's 100m backstroke - his favoured event.

Limerick's Fiona Doyle is, so far, the only Irish swimmer to have qualified for Rio.

Ryan has had two cracks at breaking the Olympic 'A' standard of 54.36 seconds, failing on both occasions in Canada and Amsterdam last year.

However, considering his personal best for the event stands at 53.84 seconds, the qualifying time should be well within his reach.

Ryan arrived in Ireland in May last year having decided to represent Ireland, but under FINA guidelines he must wait a year before he can officially swim for his adopted country.

He can still target Olympic qualification though ahead of his first major assignment for Ireland at the European Championships in London this May.

UCD’s Alex Murphy, a European Bronze medallist in the men's 50m breastroke from December’s short course [25m] finals in Israel is also competing in Luxembourg

The 50m breastroke is not an Olympic event however and the 19-year-old will be targeting the 100m breastroke time of 1:057. The heats of the mens 100m breastroke take place on Sunday.

Outside of Ryan, Swim Ireland have a squad of seven in Luxembourg including Conor Ferguson, Andrew Meegan, Jordan Sloan, Curtis Coulter, Brendan Hyland and Antoinette Neamt

Murphy and Shauna O’Brien will represent UCD at the long course [50m] meet.
