TOP rugby schools were hit with a stark warning last night from the chairman of the Irish Anti-Doping Unit that providing food supplements to adolescents was likely to lead to major health and injury issues for players in the long term.

Manchester United are attempting to negotiate a two-week trial for American teenager Freddy Adu later this month.

THE anti-doping unit of the Irish Sports Council carried out 841 tests last year including 36 tests for international federations and 79 tests under their “user pays” scheme whereby national governing bodies request and pay for additional tests.
