Williams has been one of Wales' form players this season, leading the Neath Swansea Ospreys to some notable Celtic League victories.

He called time on his 24-cap Wales career earlier this year, but new national team boss Ruddock enquired about a possible change of heart.

I recognised Barry's form by making a phone call to him, said Ruddock. I asked him to reconsider his decision to retire from international rugby.

He had been playing some excellent rugby this season and he gave it a lot of thought, but he came back to me and declined the opportunity to resurrect his international career.

I've got to respect that decision. I am disappointed, because he has been the form hooker, there is no doubt about that, but he's made his decision.

Williams, 30, toured South Africa with the 1997 Lions and last played for Wales in April 2002 against Scotland.
