All 16 teams at Euro 2008 have been given a clean bill of health after pre-tournament dope tests, organisers UEFA said on Tuesday.

Director of communications William Gaillard told a media briefing that eight to 10 players from each squad had taken part in the out-of-competition testing programme and all had returned negative results.

Gaillard said full details of the programme, which for the first time included blood and urine testing, would be announced at a news conference ahead of the opening match on Saturday.

Throughout the tournament two players from each team will be randomly selected for dope testing after every match.
