Charvis will return to Wales to play at Rodney Parade

The 84-cap former Wales captain, 33, was released by Newcastle at the end of last season and pondered retirement as he could not land a new contract.

But Michael Owen's shoulder injury left the Dragons short in the back-row, so Charvis has arrived at Rodney Parade.

Dragons coach Paul Turner said: "It was important that we secured the signing of a world-class forward and Colin fits that description."

Charvis has vast experience at international level, having also toured with the 2001 Lions.

He captained Newcastle and has also played a season for French club Tarbes after being overlooked for a contract when Wales switched from club to regional rugby.

Charvis started his career with London Welsh before joining Swansea in 1995, playing a key role in helping them claim Welsh League titles in 1998 and 2001, as well as the Welsh Cup in 1999.

"He is a big, strong forward and is a huge boost for the region. He is a proven leader and has a vast amount of experience," Turner added.

"It's a huge statement of intent and ambition. I've been talking to Colin over the last two months and I was impressed with his ambition both at regional and international level."
