William Robert Green (born 25 October 1973 in Littlehampton) was a rugby union footballer who played at prop for Wasps and Leinster.
Green began his career at Wasps, making his debut in 1995[2] and remained there until 2005. Whilst at Wasps he won the Heineken Cup in 2004,[3] the Challenge Cup in 2003[4] and the domestic Anglo-Welsh Cup (currently known as the LV Cup) in 1999[5] and 2000.[6] He was also part of the Wasps team which won the Premiership in 1996/97[7] and a further hat-trick of Premiership titles in 2003,[8] 2004[9] and 2005.[10] In the summer of 2005 he joined Leinster[11] where he remained until his retirement from the game in 2007.[12]
Green had previously played for various England youth teams alongside the likes of Will Greenwood, Matt Dawson, Simon Shaw and Richard Hill.[13] After making his England debut against Australia in November 1997, Green went on to make 4 appearances for the national team. He was considered an outside candidate to be part of Clive Woodward's ultimately victorious 2003 Rugby World Cup winning squad.[14] However, he was overlooked in the end, despite getting his 4th and final cap against Wales in one of England's warm up games prior to the World Cup,[1] and being in the wider 43-man squad.[15]
