Ulster have completed the signing of 26-year-old Dublin-born looshead prop Ruaidhri Murphy from Super Rugby franchise, the Brumbies.
Murphy has represented Ireland at schools' under-19 and under-20 level and was part of the Ireland under-20s squad that won the Grand Slam in 2007.
He came through the Leinster Academy before moving to England where he spent two seasons with the Exeter Chiefs. In 2012 he joined the Brumbies where he has made 20 appearances so far.
Murphy will link up with Ulster in August at the end of the current Super Rugby season.
"When I was deciding my future, it came down to joining Ulster or staying with the Brumbies," said Murphy.
"The Brumbies are a fantastic franchise and Canberra is a brilliant place to live, but I am Irish, I have an Irish family and I have always had the urge to return to Ireland one day and to play my rugby back home.
"Ulster are a quality team. They are currently one of the leading sides in Europe and their fans are famous around the world. It is an exciting time to be joining the Province with the new stadium and the new training facilities that have been built at Ravenhill.
"I spoke to David Humphreys about the vision that he has for Ulster- he has huge ambition and big aims for the team. That is exciting and I hope that I can play a part in bringing those aims to reality."
"Ruaidhri is a highly talented young Irish prop whose experience of Super Rugby will bring an extra dimension to our front row next season," said Director of Rugby David Humphreys.
"I am delighted that he is joining us and I have no doubt that he will be a huge success at Ravenhill in the coming years."
