Wales back row international Ollie Griffiths has received a double boost – signing a contract extension at the Dragons and returning to training after ankle surgery. The 25-year-old, who won his only cap to date as a replacement in the summer tour victory over Tonga in Auckland in 2017, has been dogged by injuries in recent seasons, but is now targeting a return to action next month. His latest problem came in the Champions Cup defeat to Wasps, when he damaged his ankle. Successful surgery was followed by rehab and now he is back running at the region’s Ystrad Mynach training base.
