LONDON (AFP) - Tommy Haas's claims that he was poisoned during Germany's Davis Cup semi-final against Russia in Moscow have been rejected by the sport's world governing body the ITF, according to a report here Monday.

The International Tennis Federation (ITF) commissioned blood tests on Haas to find out whether the German fell victim to poisoning by a third party as he had claimed.

According to a report on the BBC, blood tests have shown no evidence that Haas was poisoned during Germany's semi-final defeat by Russia in September.

A statement said: "Following enquiries, the ITF has concluded that there is no medical information or other evidence whatsoever to support recent speculation concerning the medical condition of Tommy Haas during Germany's Davis Cup semi-final tie against Russia.

"There will be no further comment on this subject."

Speaking last week, Haas said: "It's no longer an issue. The tests gave no results. It was too far in the past."

Haas was beaten in straight sets on the opening day of the semi-final, which Russia won 3-2, and was unable to play in the reverse singles due to suffering what was believed to be gastro-enteritis.

Haas was beaten in straight sets 6-2, 6-2, 6-2 by Igor Andreev in the singles as Russia claimed a 3-2 win over Germany on the weekend of September 21-23 to claim their place in the final against the USA.

The German then complained: "I have never felt so miserable in my whole life as I did on the Saturday and Sunday nights in Moscow."

"Of the eight hours I should have been sleeping, I spent six of them on the toilet."
