Warren Gatland insists he is on a self-imposed media blackout ahead of their Six Nations opener with England to prevent him "riling the opposition".
The Wales coach admits he threw a "hand grenade into the mix" when he dubbed England hooker Dylan Hartley a choker ahead of the 4 February Cardiff clash.
Gatland admits his "mischievousness" has "spiced up" the close rivalry.
"This is my last day of press," he said. "I've been banned after this. It's a self-imposed ban."
Gatland ignited the psychological mind games on Monday when he targeted Hartley as a potential weak link in the England pack when they face Wales at the Millennium Stadium on Friday week.
Wales' front row will be without influential British and Irish Lions props Adam Jones and Gethin Jenkins when Martin Johnson's England aim to win in the Welsh capital for the first time since 2003.
