Rhodri, the Wales prop, will join Dragons of Ospreys in a “long-term deal” starting in 2022-23.
For next season, the 30-year-old will join Ulster's Wales hooker Bradley Roberts as well as Irish fly-half JJhanrahan.
Dean Ryan, Dragons boss, highlighted Jones's continued ambitions for Wales.
Ryan said that Rhodri was an international-class player and is eager to produce for us.
Gareth Thomas, a fellow Osprey, is currently in the Six Nations squad. Jones was left out.
“I look forward to the next challenge. Jones stated, “I've spoken to Dean, we got on well together and I'm excited about joining,”
He stated that he was now focused solely on Ospreys, and the remainder of this season. I want to be at the top of my game before moving to Rodney Parade next season.
Jones' contract length has not been specified by Dragons.
