The pair join up with Australia’s Taqele Naiyaravo and Will Skelton, and New Zealand’s 2011 World Cup winner Andy Ellis, with more signings to be announced by coaches Robbie Deans and Will Greenwood in due course.

Both players are no strangers to the Barbarians, with Pienaar having represented the famous invitation side on three previous occasions, including the 22-21 victory over Ireland at Thomond Park last year, while Tuohy lined out for Ireland against the Baa-Baas in June 2010.

The Barbarians also face South Africa in the Killik Cup match at Wembley Stadium connected by EE on November 5 then travel to take on the Czech Republic in Prague on November 8.

Ulster scrum-half Pienaar made his international debut for South Africa against the All Blacks in 2006 and went on to make 88 appearances, helping the Springboks collect a World Cup in 2007 and the Tri-Nations two years later. Following five seasons at the Sharks, Pienaar joined Ulster in 2010 and has gone on to become a fan favourite at Kingspan Stadium, making 123 appearances and amassing 798 points along the way.

Like Pienaar, Tuohy also made his international debut against New Zealand in 2010, and marked the occasion by scoring a try within a minute of coming on to the field. Tuohy has made 11 appearances for Ireland and was part of the 2014 & 2015 Six Nations winning squads. The lock has made 123 appearances during his eight seasons at Ulster and wears the celebrated black and white shirt for the first time against Fiji.

Ulster Director of Rugby Les Kiss said: “I am delighted to announce that Ruan and Dan have been selected to join the Barbarians squad for this historic fixture. It is a great personal honour for them, and the fact that they will run out for the Barbarians here at Kingspan Stadium wearing their Ulster socks will make it an even more memorable occasion. The Barbarians and Fiji are two sides who are renowned for playing skilful and entertaining rugby so it is set up to be a fantastic night here in Belfast.”

The Barbarians and Fiji last met at Twickenham in November 2013 where the Baa-Baas recorded a 43-19 victory in a 10-try thriller. Among the try scorers that day for the Barbarians was Ulster and All Blacks' star Charles Piutau.

The Fiji squad is also likely to contain a number of high profile names, including the likes of former Ulster favourite Timoci Nagusa and Montpellier star Nemani Nadolo.
