The Welsh Rugby Union have confirmed that former British and Irish Lions centre Dr Jack Matthews has died at the age of 92.
Matthews won 17 caps for Wales, helping the side to the Grand Slam in 1950 and captaining the team against France in Paris the following year, and went on to play in six Tests for the Lions on the 1950 tour of Australia and New Zealand.
Matthews, who was known as "Iron Man" for his bone-crunching tackling, formed one of the greatest centre partnerships in the game alongside Bleddyn Williams.
Away from rugby, Matthews was a handing boxer - and famously once held Rocky Marciano to a draw in a four-round amateur bout during the Second World War.
A statement on wru.co.uk read: "Legendary Welsh centre Dr Jack Matthews has died aged 92.
"Matthews was part of a legendary Welsh midfield partnership alongside Bleddyn Williams. The former Newport and Cardiff star Matthews was also a doctor on the 1980 Lions tour of South Africa."
The Bridgend-born former Cardiff captain, whose career was curtailed by the Second World War, was made an OBE in 2001.
Matthews' former club Cardiff said in a statement: "Cardiff Rugby is saddened to have learnt of the death of Dr Jack Matthews OBE aged 92.
"Our thoughts and prayers are with his family and friends at this sad time."
