"Keep Rugby Clean is the International Rugby Board's ongoing anti-doping awareness campaign," said IRB Anti-Doping Manager Tim Ricketts. "The IRB is committed to drugs-free rugby from age grade rugby through to senior rugby and a key part of the delivery of this programme is the testing of players both in and out of competition at tournaments such as the IRB Under 19 World Championship."

"All the 24 teams at the tournament have been positive in their support of the testing and have willingly participated in a anti-doping seminar and outreach quiz, where Keep Rugby Clean t-shirts were presented to those who achieved maximum marks."

"Not only will the players, coaches, team liaison officers from the 12 Division B teams going to be wearing the t-shirts, but the match officials, tournament officials and ball boys will also be raising awareness of the campaign," added Ricketts.

The first of the IRB Under 19 Division B Round 4 matches at Bangor, Malone and Queens today kick-off at 5.30pm, with further matches at 7.30pm.

In 2006 the IRB conducted a record anti-doping test programme across a range of IRB tournaments and test matches. In total 941 doping controls were conducted, including 484 in competition tests and 457 out of competition tests that returned four positive tests.

By the time the IRB Under 19 World Championship 2007 is completed a total of 188 doping controls will have been conducted.
