"Donncha is a phenomenon. He must be one of the most professional rugby players in the world."

Second-row Donncha O'Callaghan has agreed a new one-year contract with Worcester Warriors.

The 38-year-old lock, who toured New Zealand with the British & Irish Lions in 2005 and South Africa four years later, has made 19 appearances for the Warriors in the Aviva Premiership this season and was appointed captain by new director of rugby Gary Gold.
