Tom Griffiths made one Premiership appearance for Saracens last season

Centre Tom Griffiths has joined Welsh region Dragons from English and European champions Saracens.

The Gloucester-born 23-year-old is Welsh-qualified, but has been capped at under-18 and under-20 level by England.

"Tom is a talented young centre who has spent the last four seasons working on his game in the Saracens set-up," said Dragons director of rugby Dean Ryan.

"He is keen to now really prove himself, take on a new challenge and is excited by the opportunity at Dragons."

Griffiths has also played on loan at London Scottish and Bedford Blues.
