Richard Hill was part of the England squad for the 2003 Rugby Union World Cup. During the opening game of the English campaign, against Georgia, he picked up a hamstring injury in the 50th minute.
His absence for the remaining pool games against South Africa, Samoa and the quarter final against Wales was pinpointed as a major factor as to why England looked far from the world beaters they would eventually become.
He was in the starting line up for the semi-final against France. England easily coped with the much-vaunted French back-row. Hill played a key role in helping England defeat Australia in the final.
Since Neil Back's retirement in 2003, Hill switched back to the open side flanker role. He is the only player never to have been dropped during Sir Clive Woodward's England tenure, due to his prolific work in the rucks and mauls. He played for Saracens and was selected for the England Saxons (A-Team) squad for the 2007 internationals.
Hill injured the anterior cruciate ligament in his left knee in a match against London Irish on 3 October 2004, and underwent surgery on 6 October 2004. He was out for the following seven months, but returned to be named in a Lions touring squad for the third time in 2005. He was named in the starting fifteen for the first Lions Test against the All Blacks, but suffered a knee injury during the first half, ending his tour.
In January 2008 he announced that he would retire at the end of the current Guinness Premiership season, due to the toll taken upon his knee since his two injuries - he now walks with a permanent limp. However, in April 2008, his man-of-the-match performance in the Heineken Cup victory over Ospreys confirmed his continued ability to perform at the highest level, even when playing on almost one leg.
On May 11, 2008, Hill played his last game for Saracens with a 25-20 win over Bristol.
