Maurie Fa'asavalu is a Samoan rugby union player who formerly played rugby league for St Helens. He was picked for the Great Britain national rugby league team squad in 2007, after living in England for 4 years. He returned to rugby union in October 2010, having signed for Harlequins for the 2010/2011 season.
Harlequins have managed to lure the Great Britain national rugby league team and Samoan rugby union international back to the fifteen man game. "A player of Maurie's talent and ability will be a great asset to Quins," said Quins' Director of Rugby Conor O'Shea, "I have no doubt that he will be able to make an immediate impact on returning to union. He will bring experience and a new dimension to our options and is exactly the type of person we want at this club."
Fa'asavalu made his debut on 13 March 2004 against Leeds Rhinos in a 24 – 14 victory at Knowsley Road. Fa'asavalu took some time to adjust to rugby league, but developed into an important part of the St. Helens squad in 2006. He was however used primarily as an impact player, starting most games from the interchange bench. Fas'asavalu was unlucky not to receive the Lance Todd Trophy for his performance in the 2006 Challenge Cup final victory, where he scored a try in the 2006 and his performance against Huddersfield Giants earned widespread praise. St. Helens fans were treated to Fa'asavalu's victory dance in both the 2006 Challenge Cup Final and the Grand Final for 2006's Super League XI. His block busting runs and inimitable try celebrations saw him develop a real following on the terraces at Knowsley Road. In total he scored 10 tries in 28 games during the 2006 season. St Helens reached the 2006 Super League Grand final to be contested against Hull FC and Fa'asavalu played from the interchange bench in Saints' 26-4 victory. This was followed by 9 tries in 30 games in the 2007 season. He played in 2007's Super League XIII Grand Final, 2008's Super League XIII Grand Final and 2009's Super League XIV Grand Final defeats all against the Leeds Rhinos. On 27 October 2007, Fa'asavalu scored on his debut for Great Britain against New Zealand in Huddersfield, helping the British team to a 20–14 victory. Five minutes after he came on as a substitute in the 18th minute, Fa'asavalu used his great stature to break through 3 New Zealand players to score the try.
Fa'asavalu was selected for the England squad to compete in the 2008 Rugby League World Cup tournament in Australia.Group A's first match against Papua New Guinea he played from the interchange bench in England's victory. He played 3 games for the England team in the World Cup, in the process breaking his hand in the defeat against Australia.
