Davydenko cleared of match fixing

The ATP have cleared Nikolay Davydenko of any wrongdoing following a lengthy betting probe.

An investigation was opened into irregular betting patterns after the Russian's surprise defeat at the hands of Martin Vassallo Arguello at the Sopot Open in August 2007.

Davydenko cited a foot injury as the reason behind the loss, but nevertheless found himself at the centre of an investigation surrounding the match.

In a statement on Friday the ATP confirmed there was nothing to suggest the 27-year-old had broken the rules.

"ATP can confirm today that it has concluded its investigation and found no evidence of a violation of its rules by either Mr Arguello or Mr Davydenko or anyone else associated with the match," read the statement.

The ATP's announcement follows an extensive 13-month investigation by the tennis body.

Davydenko, who denied all allegations made against him, was asked to submit his phone records as part of the probe while competing in the US Open last year.

The world number six was also controversially fined last September for not competing hard enough against Marin Cilic in the St Petersburg Open.

And the ATP revealed they were satisfied they had gone as far as they could go with their inquiries.

"During its investigation, the ATP worked with a number of leading external integrity experts," the statement continued.

"As well as interviewing a number of individuals involved in the match and reviewing betting account details of those who wagered on the match, the investigating team also requested and reviewed records from the players and from individuals closely associated with them."

"These included telephone records from individuals including Vassallo Arguello and Davydenko as well as members of both players' support personnel."

"Certain individuals declined the ATP requests and appealed them to the independent Hearing Officer."

"After lengthy legal proceedings, the independent Hearing Officer directed those individuals to turn over the requested records to ATP."

"A number of records were received and examined, however due to the length of the legal proceedings some of the records were confirmed as having been destroyed by the relevant telephone providers in line with local data protection laws."

"This confirmation means that the ATP has now exhausted all avenues of inquiry open to it and the investigation is now concluded."
