Adam Gilchrist has said comments attributed to him regarding Stuart Broad's controversial decision not to walk during the ongoing first Ashes Test were the work of a fake Twitter account.
"It has come to my attention that a fake Twitter account in my name has been making comments regarding the Stuart Broad catch in the first Test," said Australia great Gilchrist in a statement issued to AFP and other news organisations.
"I am concerned that some overseas media organisations have attributed these quotes to me," added the former Test wicketkeeper, who retired from international duty in 2008.
"Some of these fake Twitter posts may have serious legal consequences," Gilchrist said.
"While I understand the value of social media I am not on Twitter and have made no comments regarding the Stuart Broad incident."
England's Broad had made 37 on Friday when he edged teenage debutant spinner Ashton Agar to Australia captain Michael Clarke at first slip.
Australia appealed for the catch but Pakistani umpire Aleem Dar ruled in the batsman's favour as Broad stood his ground.
As Australia had by that stage used up both their reviews, there was no way for them to overturn Dar's decision even though replays showed a thick edge had deflected off wicketkeeper Brad Haddin's gloves to Clarke.
Broad's decision to stay put reopened the whole debate about 'walking', the practice where batsmen who know they've hit the ball give themselves out without waiting for the umpire's verdict, with West Indies legend Michael Holding saying he should be banned for an act contrary to the spirit of the game.
