Jason Robinson goes the groin-tackle on Prince Harry Britain's Prince Harry (foreground) jostles for the ball against former England Rugby union player Jason Robinson during a coaching session at Twickenham Stadium, west of London. Prince Harry got more than he bargained for on the rugby field when he became the object of an uncomfortable-looking tackle from former England star Jason Robinson on Thursday. Harry, 29, was taking part in a coaching session for youngsters at Twickenham when Robinson, a member of England's 2003 World Cup-winning team, grabbed the prince around the groin. The fourth in line to the throne appeared unbowed though, and threw himself into a training session with schoolgirls and schoolboys. Earlier, Robinson threw down the gauntlet to the prince, telling him: "I'll be looking to see what you've got." But Harry replied: "I think I'm a bit past it already." Harry showed off his passing, kicking and tackling skills on the famous turf, which is home to the England national side. Robinson, 39, said: "It's just fantastic to see him out here with the kids. He's dripping with sweat. He's put everything into this, because he is passionate about the game. Robinson, a fleet-footed winger in his time, also gave the prince a pair of his boots. He told him: "I can't guarantee they'll get you into the England team, but you'll be quick." As patron of the Rugby football Union (RFU), Harry is promoting a scheme to increase the amount of rugby played in state-run secondary schools and to encourage new players to join local clubs. England and Wales will host the 2015 World Cup.
