The 21-year-old centre made his Wales Sevens debut in Hong Kong in 2018 while he was in the Cardiff Blues Academy. He also played for Wales U20 during his Academy days.
Born in Penarth, he learned his rugby at Cardiff & Vale College and went on to play in nine tournaments with Wales on the World Sevens Series. He also played 11 times for Cardiff RFC over three seasons and had experience playing in the Cardiff Blues Premiership Select XV.
“I’m excited at returning to the 15s game and delighted to get the opportunity to play at a prestigious club in Ebbw Vale,” said Smith.
