Following his exit from his 20th and final Australian open, Hewitt launched a scathing attack on an online blog linking him to a report from BBC and BuzzFeed News, which claimed that 16 top players had been suspected of involvement in fixed matches but never faced action.
Sports blog Show Legend went on to publish the names of 16 players supposedly identified by BuzzFeed, with Hewitt among them.
The former Wimbledon winner called these allegations "an absolute farce" and "absurd".
"I think it's a joke to deal with it. Obviously, there's no possible way. I know my name's now been thrown into it," he told reporters at the post-match press conference.

He also was a member of the Australian teams that claimed Davis Cup honours in 1999 and 2003.
