Jonny Wilkinson denied injuring Jonathan Thomas

Wilkinson's arm smashed into Thomas' face, but there appeared to be no malice on the England star's behalf, while Wales did not make any protest.

Thomas, who left the pitch dazed and with blood seeping from his mouth, will continue to undergo tests this week.

Wilkinson has denied it was his tackle that injured the Wales flanker.

"There has been speculation that it was my tackle that led to it," he wrote in his Times column.

"I feel that it was not my tackle and it is always very sad to see a player going off injured.

"I stand firmly against foul play in the game. It has never been my desire or intention to be involved in anything like that and neither will it ever be."

Thomas, 25, is being assessed by the Wales medical team and is a doubt for Saturday's Six Nations game with Scotland at the Millennium Stadium.
