Wales international prop joins the Dragons
The 30-year-old made his Wales debut against Ireland in 2015, going on to win 39 caps.
He has not featured for Wales, though, since the 2020 Six Nations.
“We are delighted to be welcoming a player of Rob’s calibre to the Dragons and excited about the impact he can make with us,” Dragons rugby director Dean Ryan told the region’s official website.
“Rob is highly-driven and motivated to help us move forward as a squad.
“He also still has big international ambitions with Wales that he wants to achieve as a Dragon.”
