Wales prop Rhys Thomas has undergone "successful" heart surgery after being taken ill during training with club side Scarlets.

The 29-year-old was admitted to hospital in Swansea on Thursday evening. He is said to be in a "comfortable condition".

"Our thoughts and best wishes are with Rhys, his wife Paula and their family," said Scarlets chief executive Mark Davies.

"The region will be keeping in close contact with medical teams at Morriston Hospital as to his progress but it is understood that he is comfortable and doing well.

"I am sure the whole rugby community in Wales would join with us in expressing to Rhys - all our very best wishes for a quick and comfortable recovery."

Thomas's last international cap came in 2009.
